Genes affected

CLEC16A (HGNC:29013): (C-type lectin domain containing 16A) This gene encodes a member of the C-type lectin domain containing family. Single nucleotide polymorphisms in introns of this gene have been associated with diabetes mellitus, multiple sclerosis and rheumatoid arthritis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

The c.553A>G (p.M185V) alteration is located in exon 5 (coding exon 5) of the CLEC16A gene. This alteration results from a A to G substitution at nucleotide position 553, causing the methionine (M) at amino acid position 185 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
