Part Description

LP94224-0   DHCR7 gene
The DHCR7 gene (7-dehydrocholesterol reductase) [HGNC Gene ID:2860] is located on chromosome 11q13.4. This gene encodes an enzyme that removes the C(7-8) double bond in the B ring of sterols and catalyzes the conversion of 7-dehydrocholesterol to cholesterol. This gene is ubiquitously expressed and its transmembrane protein localizes to the endoplasmic reticulum membrane and nuclear outer membrane. Mutations in this gene cause Smith-Lemli-Opitz syndrome (SLOS); a syndrome that is metabolically characterized by reduced serum cholesterol levels and elevated serum 7-dehydrocholesterol levels and phenotypically characterized by mental retardation, facial dysmorphism, syndactyly of second and third toes, and holoprosencephaly in severe cases to minimal physical abnormalities and near-normal intelligence in mild cases. Alternative splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Aug 2009] [NCBI Gene ID:1717] Source: National Center for Biotechnology Information (NCBI) Gene

Change Reason
Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
