Genes affected

LY6G6D (HGNC:13935): (lymphocyte antigen 6 family member G6D) LY6G6D 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, Apr 2009]

Ambry Genetics

Jan 10, 2023

The c.74A>G (p.Y25C) alteration is located in exon 2 (coding exon 2) of the LY6G6D gene. This alteration results from a A to G substitution at nucleotide position 74, causing the tyrosine (Y) at amino acid position 25 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
