            The five beta-like globin genes are found within a 45 kb cluster on
            chromosome 11 in the following order:
            
            
            
            
                  5'-epsilon -G-gamma -A-gamma -delta -beta-3'   [22]
            
            
            
            Additionally, the pseudogene beta-1 is located between the A-gamma
            and delta genes [72]. A region 5' to the epsilon gene was thought
            to be another pseudogene; however [55] shows this not to be so.
            These embryonic, fetal and adult beta-like genes have the same
            overall exonic structure, leading to the conclusion that they are
            derived from one ancestral gene. In particular, they have many
            consensus sequences and repetitive sequences in common which have
            been analyzed by [27] and [76].
            
            
            
            
                   Epsilon gene
                   ------------
            
            
            
            The epsilon globin gene (hbe below) is normally expressed in the
            embryonic yolk sac: two epsilon chains together with two zeta
            chains (an alpha-like globin; see separate entry) constitute the
            embryonic hemoglobin Hb Gower I; two epsilon chains together with
            two alpha chains form the embryonic Hb Gower II.  Both of these
            embryonic hemoglobins are normally supplanted by fetal, and later,
            adult hemoglobin.
            
            
            
            The promoter region sequences 'ccaat', 'ata' and 'cttccg' found at
            19403, 19458 and 19495 are characteristic of all human beta-like
            genes, as well as of some other mammalian genes, and are thought to
            influence initiation of transcription and translation [27],[76].
            However, at least nine alternative cap sites which do not possess
            these conserved sequences have been found upstream from the
            so-called canonical cap sites at 19486 and 19488 [52],[60].
            
            
            
            The Alu family sequences found at 16892-17158 and 17927-18190 are
            typical of the 5' flanking regions of the beta-like globin genes
            [23],[39]. The first of these bipolar repeats has been shown to be
            active as a template for RNA polymerase III [39].
            
            
            
            
                   G-gamma and A-gamma genes
                   -------------------------
            
            
            
            The gamma globin genes (hbgg and hbga below) are normally expressed
            in the fetal liver, spleen and bone marrow.  Two gamma chains
            together with two alpha chains constitute fetal hemoglobin (HbF)
            which is normally replaced by adult hemoglobin (HbA) at birth.  In
            some beta-thalassemias and related conditions (HPFH or 'hereditary
            persistence of fetal hemoglobin'), gamma chain production continues
            into adulthood.  The mapping of deletions in these pathologies is
            therefore of special interest with regard to developmental control
            mechanisms.
            
            
            
            The two types of gamma chains differ at residue 136 where glycine
            is found in the G-gamma product and alanine is found in the A-gamma
            product.  The former is predominant at birth.  Because of the
            sequence identity of the two genes over large stretches, it was not
            always possible in the early work to know which sequence was being
            investigated [13],[15],[17].  Moreover, because allelic variation
            has been reported for each of these non-allelic genes, further
            sequence work is required to determine the consensus sequence for
            each.  Thus far the sequences of two A-gamma alleles have been
            reported ([24]; see separate entry which annotates the allelic
            variation).  The second introns for the hbgg and hbga genes shown
            below contain 886 and 866 bases respectively, while their alleles
            on the opposing chromosome have 904 and 876 bases for the
            corresponding introns.  [24] and [29] present an analysis of this
            phenomenon and conclude that intergenic exchange can occur in human
            germ line cells with significant frequency.
            
            
            
            Given the above-mentioned uncertainties with regard to polymorphism
            and material, differences, where annotated, are treated as
            variations rather than as conflicts.
            
            
            
            The promoter region sequences 'ccaat', 'ata' and 'cttctg' found at
            bases 34390, 34448 and 34485 in the hbgg gene, and bases 39326,
            39384 and 39421 in the hbga gene, are characteristic of all
            beta-like genes, as well as of some other mammalian genes, and are
            thought to influence transcription and translation [27],[76].  The
            gamma genes each manifest duplicate 'ccaat' boxes at positions
            34363 (hbgg) and 39299 (hbga).  Alternative cap sites are active in
            vitro upstream from the canonical cap sites at 34478 and 39414: at
            bases 34398, 34408, 34418 and 34428 for hbgg, and at bases 39334,
            39344, 39354 and 39364 for hbga [73].  Alternative cap sites have
            also been reported for epsilon and beta mRNAs when there is no
            duplication of the 'ccaat' sequence.  [81] and [82] show that the
            distal 'ccaat' box for the hbga gene (for the B allele -- see
            separate sequence) has some vital function: a g -> a mutation at
            base 39297 is apparently responsible for one form of Greek HPFH.
            
            
            
            The Alu family sequences found at bases 32390-32723 (approx.) and
            37325-37562 (approx.) are typical of the beta-like globin Alu's
            [27],[76],[31],[29].  A study of the hbgg repeat has revealed RNA
            transcription by polymerase III [31]( also reported for Alu regions
            in the 5' flanks of the epsilon and beta genes).
            
            
            
            
                   Pseudo-beta-1
                   -------------
            
            
            
            Human, gorilla and chimpanzee beta-like pseudogenes were sequenced
            and compared (see separate entries for the other primate sequences)
            by [72] and revised by [94]. The pseudogene structure was deduced
            through comparison with the A-gamma globin gene. Base substitutions
            in the initiation codon and in codons downstream, that create
            internal termination signals in exons 2 and 3, make this sequence a
            pseudogene.
            
            
            
            
                   Delta and beta genes
                   --------------------
            
            
            
            The delta and beta genes (denoted hbd and hbb below) are normally
            expressed in the adult: two alpha chains plus two beta chains
            constitute HbA, which in normal adult life comprises about 97% of
            the total hemoglobin.  Two alpha chains plus two delta chains
            constitute HbA-2, which with HbF comprises the remaining 3% of
            adult hemoglobin.
            
            
            
            The sequence given below has been reconstructed from the sequences
            reported by [47] and [62]: the mutation at base 62143 is apparently
            sufficient to distinguish the Kurdish Jew thalassemic sequence from
            a normal (consensus) beta globin DNA; [62] has resolved all
            sequence differences to date with exception of the differences
            reported herein as variations.
            
            
            
            The promoter region sequences 'ccaat', 'ata' and 'cttctg' found at
            bases 54672, 54709 and 54747 in the delta gene, and at bases 62061,
            62106 and 62144 in the beta gene, are characteristic of all
            beta-like genes, as well as of some other mammalian genes, and are
            thought to influence transcription and translation [27],[76].
            However, alternative cap sites have been found for these genes as
            well as other beta-like genes [58],[73].
            
            
            
            [95] describes the mutation (substitution of 'a' for 't' at
            position 62107, thereby destroying the promoter) found in an Hb
            Lepore-beta+ -thalassemia patient, who was homozygous for this
            mutation.  The father who had the simple beta-thalassemia trait was
            found to be heterozygous.
            
            
            
            A form of thalassemia exists, where 19 bp are added after the first
            exon, starting at position 62390 and ending at a stop codon at
            position 62406-62408 [30],[43],[57]. This aberrant splicing is
            caused by a mutation of 'g' to 'a' in the first intron of
            beta-hemoglobin at position 62388.  The substitution of a 'g' for a
            't' at position 62394 also causes premature splicing and results in
            an abnormal and abbreviated beta hemoglobin [90].
            
            
            
            Another form of beta-thalassemia is produced by the substitution of
            an 'a' for a 'g' at position 62632.  This causes a readthrough at
            the exon/intron boundary of exon 2/intron 2 [44].
            
            
            
            The Alu family sequences found at bases 50915, 51976, 65513 and
            66776 are again typical of the beta-like globin Alu's.  These
            sequences are of considerable interest in relation to regulation,
            recombination and transcription by RNA polymerase III.
            
            
            
            There are non-Alu repetitive elements in the gene cluster that have
            been partially characterized: the EC-1 repeat [38] and a
            retrovirus-like element in the 3' flank about 300 kb downstream of
            this sequence [75] (see separate entry); there are numerous repeats
            in the 5' flank which will be included in a future update [80].
            Reference [83] has characterized a novel KpnI family sequence in
            the 3' flank of the cluster.
            
            
            
            Potential polyadenylation signals were identified for the following
            genes:
               hbe       positions 21055-21060
               hbgg      positions 36043-36048
               hbga      positions 40959-40964
               hbd       positions 56365-56370
               hbb       positions 63718-63723.
