Genes affected

CLEC2A (HGNC:24191): (C-type lectin domain family 2 member A) Enables protein homodimerization activity. Predicted to be involved in natural killer cell mediated cytotoxicity. Predicted to act upstream of or within several processes, including T cell receptor signaling pathway; regulation of actin filament polymerization; and regulation of interleukin-2 production. Located in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.325G>A (p.A109T) alteration is located in exon 4 (coding exon 4) of the CLEC2A gene. This alteration results from a G to A substitution at nucleotide position 325, causing the alanine (A) at amino acid position 109 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
