Genes affected

CLEC12A (HGNC:31713): (C-type lectin domain family 12 member A) This gene encodes a member of the C-type lectin/C-type lectin-like domain (CTL/CTLD) superfamily. Members of this family share a common protein fold and have diverse functions, such as cell adhesion, cell-cell signaling, glycoprotein turnover, and roles in inflammation and immune response. The protein encoded by this gene is a negative regulator of granulocyte and monocyte function. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. This gene is closely linked to other CTL/CTLD superfamily members in the natural killer gene complex region on chromosome 12p13. [provided by RefSeq, May 2011]

The c.638T>C (p.M213T) alteration is located in exon 6 (coding exon 6) of the CLEC12A gene. This alteration results from a T to C substitution at nucleotide position 638, causing the methionine (M) at amino acid position 213 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
