Genes affected

COLEC10 (HGNC:2220): (collectin subfamily member 10) This gene encodes a member of the C-lectin family, proteins that possess collagen-like sequences and carbohydrate recognition domains. The other members of this family are secreted proteins and bind to carbohydrate antigens on microorganisms facilitating their recognition and removal. This gene product is a cytosolic protein, a characteristic that suggests that it may have different biological functions than other C-lectins. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.22C>T (p.L8F) alteration is located in exon 1 (coding exon 1) of the COLEC10 gene. This alteration results from a C to T substitution at nucleotide position 22, causing the leucine (L) at amino acid position 8 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
