Genes affected

LY6G5B (HGNC:13931): (lymphocyte antigen 6 family member G5B) LY6G5B 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.191T>C (p.V64A) alteration is located in exon 3 (coding exon 3) of the LY6G5B gene. This alteration results from a T to C substitution at nucleotide position 191, causing the valine (V) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
