| IDENTIFICATION OF SPECIES OF ORIGIN |
Species of Origin Confirmed by Nucleoside Phosphorylase Isoenzyme Electrophoresis |
| |
| Gene |
ARH |
| Chromosomal Location |
1p36-p35 |
| Allelic Variant 1 |
605747.0003; HYPERCHOLESTEROLEMIA, AUTOSOMAL RECESSIVE |
| Identified Mutation |
GLN136TER; In a Lebanese family with autosomal recessive hypercholesterolemia (603813), Garcia et al. (2001) found that all affected individuals were homozygous for a C-to-T transition at nucleotide 406 of the ARH gene, resulting in a glu-to-ter substitution at codon 136 (Q136X). |

| Remarks |
Lebanese; large xanthomas; product of a consanguineous mating; fasting plasma total cholesterol of 440 milligram per microliter; LDLR activity in fibroblasts was 60-70% of normal controls; 3 affected sibs, GM00667, GM00694, GM00696; donor subject is homozygous for a C-to-T transition at nucleotide 406 (c.406C>T) in exon 4 of the ARH gene, resulting in a nonsense mutation in codon 136, a glutamine-to-ter substitution [Gln136TER (Q136X)]. |
