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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.164G>A (p.C55Y) alteration is located in exon 2 (coding exon 2) of the LY6G5B gene. This alteration results from a G to A substitution at nucleotide position 164, causing the cysteine (C) at amino acid position 55 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
