| Gene |
SLC17A5 |
| Chromosomal Location |
6q14-q15 |
| Allelic Variant 1 |
604322.0001; SALLA DISEASE |
| Identified Mutation |
ARG39CYS; In 5 Finnish patients with classic Salla disease (604369), Verheijen et al. (Nature Genet. 23: 462-465, 1999) found an arg39-to-cys (R39C) missense mutation caused by a homozygous C-to-T transition at nucleotide 115 of the SLC17A5 gene. Aula et al. (Am. J. Hum. Genet. 67: 832-840, 2000) found that the homozygous R39C mutation was associated with a milder phenotype (Salla disease). |

| Remarks |
Clinically affected; no family history; normal newborn period; hypotonia during first months of life; ocular squint at 3 months; ataxia at 6 months; walking with aid at 3 years, later unable to walk; delayed speech, at 5 years only able to say a few words or simple sentences; severe mental retardation; urinary free sialic acid 98 micromole/mmole creatinine (control = 14); donor subject is homozygous for the Finnish founder mutations: a C-to-T transition at nucleotide 115 (115C>T) in exon 2 of the SLC17A5 gene which results in a missense mutation [ARG39CYS (R39C)]. |
