| Identified Mutation |
GLY216ARG; In a patient, GM11411, with very severe combined immunodeficiency, Hirschhorn et al. [Am J Hum Genet 49: 878 (1991)] identified a transition of G-646 to A at a CG dinucleotide, predicting a glycine-to-arginine substitution at codon 216 of the ADA protein.The patient was homozygous, the offspring of consanguineous Amish parents from eastern Pennsylvania. Onset of symptoms was at 3 days of age with respiratory distress from pneumonia unresponsive to antibiotics. |

| Identified Mutation |
ARG156HIS; In 3 patients with delayed or late onset of SCID due to ADA deficiency (102700), Santisteban et al. [J Clin Invest 92:2291-2302,1993] identified a heterozygous 467G-A transition in exon 5 of the ADA gene at a CpG hotspot, resulting in an arg156-to-his (R156H) substitution. All 3 patients were compound heterozygous for R156H and a mutation predicted to result in an inactive enzyme; 1 patient also carried the G216R (608958.0016) mutation. Functional expression studies showed that the R156H mutant enzyme retained 1.5 to 2% residual activity. |
| Remarks |
Clinically affected; donor subject is a compound heterozygote: one allele has a G>A transition at nucleotide 646 in exon 7 of the ADA gene [646G>A] resulting in a substitution of arginine for glycine at codon 216 [Gly216Arg (G216R)]; a second allele has a G>A transition at nucleotide 467 in exon 5 resulting in a substitution of histidine for arginine at codon 156 [Arg156His (R156H)] |
