Remarks

Clinically affected; deficient ADA activity in lymphoblasts and mononuclear cells; enzyme phenotypes: 6PGD=A, G6PD=B, Peptidases A,C,and D=1, Acid Aglucosidase=1, Neutral A-glucosidase C= 3-2; normal ADA mRNA level; donor subject is a compound heterozygote: one allele has a G>A transition at nucleotide 727 in exon 7 of the ADA gene [727G>A (alternately described as 632G>A)] resulting in a substitution of histidine for arginine at codon 211 [Arg211His (R211H)] and a second allele has a C>T transition at nucleotide 1081 in exon 11 of the ADA gene [1081C>T] resulting in a substitution of valine for alanine at codon 329 [Ala329Val (A329V)].

Wiginton et al (J Biol Chem 257:3211-3217 1982) observed that this cell culture contained < 5% of normal ADA activity and immunoreactive protein. Adrian et al (Hum Genet 68:169-172 1984) reported that this ADA-deficient cell culture had normal relative levels of ADA mRNA. Sequence analysis of cDNA clones synthesized from ADA mRNA from this culture revealed a different point mutation in each allele that causes amino acid changes. In one allele amino acid 329 is changed from alanine to valine (GCG>GTG at position #1081). In the second allele amino acid 211 is changed from arginine to histidine (CGT>CAT at position 727). In addition to these point mutations each allele has a point mutation in the third base of a codon that does not alter the amino acid encoded (Ser-110 is TCT rather than TCC and Val-629 is GTA rather than GTG). Analysis of additional clones of each of these alleles showed unusual characteristics which suggest occasional aberrant splicing of ADA pre-mRNA (Akeson et al Proc Natl Acad Sci USA 84:59475951 1987). Akeson et al (J Biol Chem 263:16291-16296 1988) inserted the mutant ADA cDNA from this cell line into an expression vector and tested it in a transient expression system. ADA mRNA transcribed from the mutant vector failed to produce significant levels of enzymatically active ADA while ADA mRNA transcribed from a vector with the normal ADA cDNA did produce high levels of enzymatically active ADA. These authors also noted that the point mutation at amino acid no. 211 (Arg to His) resulting from a point mutation at base no. 727 (G to A) was also observed in another ADA-deficient cell line (GM02606) and the mutation in amino acid no. 329 (Ala to Val) resulting from a point mutation at base no. 1081 (C to T) had been observed for a different ADA-deficient cell line (GM02825). EC Number: 3.5.4.4; <5% activity.

Identified Mutation

ARG211HIS; Akeson et al. [J Biol Chem 263:16291 (1988)] found this change, a 632G-A transition in the ADA gene, resulting in the replacement of the arginine residue by histidine at codon 211, in cell line GM02606 and Akeson et al. [Proc Natl Acad Sci U S A 84: 5947 (1987)] found it in cell line GM02756.

Identified Mutation

ALA329VAL; In GM02756, Akeson et al. [Proc Natl Acad Sci U S A 84: 5947 (1987)] demonstrated 2 different mutant alleles: one was ala329 to val; the other was a 632G-A transition in the ADA gene, resulting in the replacement of the arginine residue by histidine at codon 211 (102700.0004). In addition, Akeson et al. [Proc Natl Acad Sci U S A 84: 5947 (1987)] and [J Biol Chem 263:16291 (1988)] found that cell line GM02825A was a genetic compound. One allele had an ala329-to-val change (102700.0006); the other allele had a point mutation from A to G in the 3-prime splice site of intron 3 (102700.0017), resulting in elimination of exon 4 from the mature mRNA.
