Genes affected
MSMO1 (HGNC:10545): (methylsterol monooxygenase 1) Sterol-C4-mehtyl oxidase-like protein was isolated based on its similarity to the yeast ERG25 protein. It contains a set of putative metal binding motifs with similarity to that seen in a family of membrane desaturases-hydroxylases. The protein is localized to the endoplasmic reticulum membrane and is believed to function in cholesterol biosynthesis. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 29, 2023 | The c.38C>T (p.A13V) alteration is located in exon 2 (coding exon 1) of the MSMO1 gene. This alteration results from a C to T substitution at nucleotide position 38, causing the alanine (A) at amino acid position 13 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
