Nagasawa et al (Cancer Res 47:398-402,1987) observed that this cell culture derived from an Ataxia telangiectasia heterozygote showed a sensitivity to the cytotoxic effects of X-irradiation intermediate between that of AT homozygous and normal cell strains. |

| Allelic Variant 1 |
W2638X; ATAXIA-TELANGIECTASIA |
| Identified Mutation |
TRP2638TER |
| Remarks |
Clinically unaffected; normal sensitivity to cell killing by X-irradiation; 2 affected children including GM03395; same donor as GM03334 Lymphoblast; donor subject has a G>A transition at nucleotide 7913 in exon 55 of the ATM gene (7913G>A) resulting in a substitution of a termination codon for tryptophan at codon 2638 [Trp2638Ter (W2638X)] on one allele |
