Genes affected

CLEC1B (HGNC:24356): (C-type lectin domain family 1 member B) Natural killer (NK) cells express multiple calcium-dependent (C-type) lectin-like receptors, such as CD94 (KLRD1; MIM 602894) and NKG2D (KLRC4; MIM 602893), that interact with major histocompatibility complex class I molecules and either inhibit or activate cytotoxicity and cytokine secretion. CLEC2 is a C-type lectin-like receptor expressed in myeloid cells and NK cells (Colonna et al., 2000 [PubMed 10671229]).[supplied by OMIM, Jan 2011]

The c.353G>C (p.R118T) alteration is located in exon 4 (coding exon 4) of the CLEC1B gene. This alteration results from a G to C substitution at nucleotide position 353, causing the arginine (R) at amino acid position 118 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
