| Allelic Variant 1 |
608958.0010; ADA DEFICIENCY, PARTIAL |
| Identified Mutation |
ARG76TRP; In cell lines GM05816, GM06200 and GM07103, Hirschhorn et al. [Proc Natl Acad Sci U S A 87: 6171 (1990)] found a C-to-T transition at nucleotide 226 resulting in a change of arginine-76 to tryptophan. |
| Remarks |
Clinically unaffected; 50% of adenosine deaminase activity in RBCs; 50% of normal purine nucleoside phosphorylase activity; 91% of normal ADA activity in lymphoblasts; donor subject has one allele which has a C>T transition at nucleotide 226 in exon 4 of the ADA gene [226C>T] resulting in a substitution of tryptophan for arginine at codon 76 [Arg76Trp(R76W)]; affected child is GM05816. |
