Genes affected

CLEC12B (HGNC:31966): (C-type lectin domain family 12 member B) Enables protein phosphatase binding activity and signaling receptor inhibitor activity. Involved in natural killer cell inhibitory signaling pathway; negative regulation of natural killer cell mediated cytotoxicity; and negative regulation of signaling receptor activity. Located in external side of plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

CLEC12B links:

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.185T>C (p.M62T) alteration is located in exon 2 (coding exon 2) of the CLEC12B gene. This alteration results from a T to C substitution at nucleotide position 185, causing the methionine (M) at amino acid position 62 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
