Genes affected

CLNK (HGNC:17438): (cytokine dependent hematopoietic cell linker) MIST is a member of the SLP76 family of adaptors (see LCP2, MIM 601603; BLNK, MIM 604515). MIST plays a role in the regulation of immunoreceptor signaling, including PLC-gamma (PLCG1; MIM 172420)-mediated B cell antigen receptor (BCR) signaling and FC-epsilon R1 (see FCER1A, MIM 147140)-mediated mast cell degranulation (Cao et al., 1999 [PubMed 10562326]; Goitsuka et al., 2000, 2001 [PubMed 10744659] [PubMed 11463797]).[supplied by OMIM, Mar 2008]

The c.494C>G (p.P165R) alteration is located in exon 11 (coding exon 10) of the CLNK gene. This alteration results from a C to G substitution at nucleotide position 494, causing the proline (P) at amino acid position 165 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
