Genes affected

LY6G6C (HGNC:13936): (lymphocyte antigen 6 family member G6C) LY6G6C belongs to a cluster of leukocyte antigen-6 (LY6) genes located in the major histocompatibility complex (MHC) class III region on chromosome 6. Members of the LY6 superfamily typically contain 70 to 80 amino acids, including 8 to 10 cysteines. Most LY6 proteins are attached to the cell surface by a glycosylphosphatidylinositol (GPI) anchor that is directly involved in signal transduction (Mallya et al., 2002 [PubMed 12079290]).[supplied by OMIM, Mar 2008]

The c.106C>T (p.R36W) alteration is located in exon 2 (coding exon 2) of the LY6G6C gene. This alteration results from a C to T substitution at nucleotide position 106, causing the arginine (R) at amino acid position 36 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
