Genes affected

COLEC11 (HGNC:17213): (collectin subfamily member 11) This gene encodes a member of the collectin family of C-type lectins that possess collagen-like sequences and carbohydrate recognition domains. Collectins are secreted proteins that play important roles in the innate immune system by binding to carbohydrate antigens on microorganisms, facilitating their recognition and removal. The encoded protein binds to multiple sugars with a preference for fucose and mannose. Mutations in this gene are a cause of 3MC syndrome-2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The COLEC11 c.19A>T variant is predicted to result in the amino acid substitution p.Ser7Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.058% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
