Genes affected

UQCC1 (HGNC:15891): (ubiquinol-cytochrome c reductase complex assembly factor 1) This gene encodes a transmembrane protein that is structurally similar to the mouse basic fibroblast growth factor repressed ZIC-binding protein. In mouse this protein may be involved in fibroblast growth factor regulated growth control. In humans, polymorphisms in this gene are associated with variation in human height and osteoarthritis. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Ambry Genetics

Oct 25, 2024

The c.496C>T (p.R166W) alteration is located in exon 7 (coding exon 7) of the UQCC1 gene. This alteration results from a C to T substitution at nucleotide position 496, causing the arginine (R) at amino acid position 166 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
