Genes affected
COLEC12 (HGNC:16016): (collectin subfamily member 12) This gene encodes a member of the C-lectin family, proteins that possess collagen-like sequences and carbohydrate recognition domains. This protein is a scavenger receptor that displays several functions associated with host defense. It can bind to carbohydrate antigens on microorganisms, facilitating their recognition and removal. It also mediates the recognition, internalization, and degradation of oxidatively modified low density lipoprotein by vascular endothelial cells. [provided by RefSeq, May 2018]

The c.800C>T (p.T267M) alteration is located in exon 5 (coding exon 5) of the COLEC12 gene. This alteration results from a C to T substitution at nucleotide position 800, causing the threonine (T) at amino acid position 267 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
