| Allelic Variant 1 |
604611.0004; WERNER SYNDROME |
| Identified Mutation |
IVS25DS, G>C, -1, FS1061TER; In a Japanese patient with Werner syndrome (277700), Yu et al. [Science 272: 258-262 (1996)] detected a G-to-C transversion in the WRN gene that changed a splice donor sequence from ApG to ApC, resulting in a frameshift of codons 1078 to 1092. The premature stop codon which is a consequence of this frameshift results in a predicted 1060-amino acid truncated protein. |

| Remarks |
JO1050: 57 year old Japanese male of first cousin marriage. Cataracts, tight skin, short stature, type II diabetes mellitus, osteoporosis, high pitched voice, flat feet. Homozygous mutation at WRN locus: a G to C transversion in the RECQL2 gene changes a splice donor sequence from ApG to ApC, resulting in a frameshift of codons 1078 to 1092 and a skipping of exon 26. The mutation is designated IVS25-1G>C. The karyotype is 46,XY, der(8)(8qter>8p11::12q11>12qter), +mar with 2% of the cells examined showing random chromosome loss and 2% showing random chromosomal aberrations. The legacy karyotype description shown in this Remark may not be representative of the current available product. |
