608958.0013; SEVERE COMBINED IMMUNODEFICIENCY, AUTOSOMAL RECESSIVE, T CELL-NEGATIVE, B CELL-NEGATIVE, NK CELL-NEGATIVE, DUE TO ADENOSINE DEAMINASE DEFICIENCY |
| 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. |
| Remarks |
Clinically affected; Sephardic Jewish; classical early onset severe form; ADA activity deficient in erythrocytes, fibroblasts, and lymphoblast culture; donor subject has one allele that 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)]. |
