Gene: [11q13/DHCR7] 7-dehydrocholesterol reductase; delta-7-dehydrocholesterol reductase; Smith-Lemli-Opitz syndrome, type 1? (MIM:270400);
| 
 COM  | 
Using radiation hybrid mapping, Wassif-1998 showed that the DHCR7 gene is located at 11q12-q13. By fluorescence in situ hybridization mapping, Waterham-1998 assigned the DHCR7 gene to 11q13." | 
| 
 FUN  | 
In cholesterol biosynthesis, the sterol delta-7-reductase converts 7-dehydrocholesterol to cholesterol." | 
| 
 PAT  | 
[1] Children with the Smith-Lemli-Opitz syndrome, a frequent inborn
disorder
of sterol metabolism, have elevated serum levels and low serum
cholesterol levels. So delta-7-sterol reductase is suspected to be
defective in this syndrome (Moebius-1998).
 [2] Another locus associated with Smith-Lemli-Opitz syndrome was found: GEM:07q321/SLOS."  |
