Genes affected

CLEC2D (HGNC:14351): (C-type lectin domain family 2 member D) This gene encodes a member of the natural killer cell receptor C-type lectin family. The encoded protein inhibits osteoclast formation and contains a transmembrane domain near the N-terminus as well as the C-type lectin-like extracellular domain. Several alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Oct 2010]

The c.325G>A (p.D109N) alteration is located in exon 3 (coding exon 3) of the CLEC2D gene. This alteration results from a G to A substitution at nucleotide position 325, causing the aspartic acid (D) at amino acid position 109 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
