300126.0002; DYSKERATOSIS CONGENITA, X-LINKED |
| Identified Mutation |
LEU37 DEL; In a patient with dyskeratosis congenita, Heiss et al. (1998) found deletion of nucleotides 201 to 203 (CTT), leading to deletion of leucine-37 from dyskerin.

See GM01774A Fib; HLA type Aw30,(Bw40), B13,B5; maternal grandfather was also affected; leukoplakia tongue; dysplastic finger and toenails; fibro show increased BrdU induced chromosome instability and hypersens to mitomycin-C induced cell killing; donor subject is hemizygous for an in frame 3 bp deletion of nucleotides 201_203 of the DKC1 gene (201_203delCTT) resulting in the deletion of leucine at position 37 [Leu37del] |
