| Allelic Variant 1 |
609523.0003; SJOGREN-LARSSON SYNDROME |
| Identified Mutation |
3-BP DEL/21-BP INS, ALA314GLY, PRO315ALA; In a 5-year-old girl with Sjogren-Larsson syndrome born to consanguineous parents of mixed European origin, De Laurenzi et al. [Nature Genet. 12: 52-57 (1996)] found a 3-bp deletion of the FALDH gene (NT941-943) combined with a 21-bp insertion in both alleles. This mutation resulted in ala314-to-gly and pro315-to-ala substitutions with insertion of 6 amino acids (A-K-S-T-V-G) between the pair. Significantly, pro315 is invariably conserved among 16 other ALDHs and is therefore likely to have an essential role in enzyme function. |

| Remarks |
Congenital ichthyosis; mental retardation; spastic quadriplegia; fibroblasts have 5% of control fatty alcohol:NAD+ oxidoreductase activity using octadecanol as the substrate; donor subject is homozygous for a 3 bp deletion at nucleotide 941 with a 21 bp insertion at the intron 6/exon 7 junction of the ALDH3A2 gene (941_943delCCC + ins21nt) leading to amino acid substitutions [Ala314Gly (A314G)] and [Pro315Ala (P315A)] accompanied by the addition of six amino acids, Ala-Lys-Ser-Thr-Val-Gly between the pair |
