| Allelic Variant 1 |
609523.0006; SJOGREN-LARSSON SYNDROME |
| Identified Mutation |
2-BP DEL, 1297GA; In a patient with Sjogren-Larsson syndrome, Tsukamoto et al. [Ann. Hum. Genet. 61: 235-242 (1997)] found a 2-bp deletion at nucleotide 1297 of the ALDH10 gene, with consequent premature chain termination at protein position 434. |
| Remarks |
Mildly affected with congenital ichthyosis, mental retardation, & spastic diplegia of lower extremities; fibroblasts have 8% of control fatty alcohol:NAD+ oxidoreductase activity using octadecanol as substrate; donor subject is a compound heterozygote: allele 1 has a 2 bp deletion at nucleotide 1297 of the ALDH3A2 gene (1297_1298delGA) with consequent premature termination at amino acid 434 and the other allele carries an as yet unidentified mutation. |
