| Identified Mutation |
ARG149GLN; In cell line GM06143A, Hirschhorn et al. [Proc Natl Acad Sci U S A 87: 6171 (1990)] found a substitution of glutamine for arginine at amino acid 149 resulting from a G-to-A transition at nucleotide 446. |

| Allelic Variant 2 |
608958.0009; ADA DEFICIENCY, PARTIAL |
| Identified Mutation |
PRO297GLN; In a partially ADA-deficient child from Santo Domingo, Hirschhorn et al. (1989) demonstrated a C-to-A transversion that resulted in the replacement of a proline by a glutamine residue at codon 297. Since this mutation generated a new recognition site in exon 10 of genomic DNA for the enzyme AluI, Hirschhorn et al. (1989) could use Southern blot analysis to establish that this child was homozygous for the mutation and that the same mutation was present in another patient. The point mutation resulted in heat-lability of the enzyme.

| Remarks |
Phenotypically normal; Santo Domingan; partial ADA deficiency; several intermittent infections; normal growth and development; <1% normal ADA activity in RBCs; normal ADA activity in peripheral blood mononuclear cells; percentage of T cells normal; normal response to mitogens; 86% of normal ADA activity in lymphoblasts; donor subject is a compound heterozygote: one allele has a G>A transition at nucleotide 446 in exon 5 of the ADA gene [446G>A] resulting in a substitution of glutamine for arginine at codon 149 [Arg149Gln (R149Q)] and a second allele has a C>A transversion in exon 10 of the ADA gene resulting in a substitution of glutamine for proline at codon 297 [Pro297Gln (P297Q)]; affected sibling; parents are GM06415 and GM06416. |
