| Chromosomal Location |
8p12-p11.2 |
| Allelic Variant 1 |
604611.0006; WERNER SYNDROME |
| Identified Mutation |
ARG368TER; In 1 Caucasian and 3 Japanese patients with Werner syndrome (277700), Oshima et al. [Hum. Molec. Genet. 5: 1909-1913 (1996)] first reported this mutation (1336C-T), located in exon 9 of the WRN gene, that was predicted to produce a truncated protein lacking WRN helicase function. |

| Remarks |
LGS90610: 48 year old caucasian female. Bilateral ocular cataracts, tight atrophic skin, short stature, type II diabetes mellitus, hypogonadism, osteoporosis, soft tissue calcification, coronary artery disease, medial calcinosis. No parental consanguinity. The donor subject is homozygous for a C>T transition at nucleotide 1336 in exon 9 of the RECQL2 gene (1336C>T) resulting in an amino acid change at codon 368 from arginine to a stop codon [Arg368Ter (R368X)]. The karyotype is 46,XX,t(15;20)(15pter>15q26.2::20q13.2>20qter;20pter>20q13.2::15q26.2>15qter) with 8% of the cells examined showing random chromosome loss/gain. The legacy karyotype description shown in this Remark may not be representative of the current available product. |
