| Identified Mutation |
LEU107PRO; In GM07103 and GM04396, both cell lines from compound heterozygous patients, Hirschhorn et al. [Proc Natl Acad Sci U S A 87: 6171 (1990)] found a substitution of proline for leucine at amino acid 107 resulting from a T-to-C transition in nucleotide 320 in exon 4. |

ARG211CYS; In cell line GM04396, from a compound heterozygous patient, Hirschhorn et al. [Proc Natl Acad Sci U S A 87: 6171 (1990)] found substitution of cysteine for arginine at amino acid 211 resulting from a C-to-T transition of nucleotide 631. |
| Remarks |
Phenotypically normal; erythrocyte ADA deficiency diagnosed as part of a newborn screening program; transient diaper rash and oral thrush in first months of life; in first 2 years of life had a few colds and several episodes of otitis media; normal development with height and weight at 90th percentile; total lymphocyte counts were normal with 70% T cells on repeated determinations; delayed hypersensitivity to Candida albicans and mumps was present; responses of peripheral lymphocytes to PHA and allogeneic cells were normal; immunoglobulin levels rose appropriately with age; radiographs of chest, skull, and pelvis were normal; ADA activity in erythrocytes is undetectable; ADA enzyme activity in peripheral lymphocytes is 0.9% of control values with an immunoreactive ADA protein present at 1.6% of normal CRM; ADA activity and immunoreactive protein in lymphoblast culture detectable at 4% of control; ADA activity in fibroblasts detectable at 14% of control; dATP in RBC's is elevated; parents and brother have heterozygous levels of ADA activity; donor subject is a compound heterozygote: one allele has a T>C transition at nucleotide 320 in exon 4 of the ADA gene [320T>C] resulting in a substitution of proline for leucine at codon 107 [Leu107Pro (L107P)] and a second allele has a C>T transition at nucleotide 631 of the ADA gene [631C>T] resulting in a substitution of cysteine for arginine at codon 211 [Arg211Cys (R211C)]; same donor as GM04396 lymphocyte. |
