Genes affected

LY6G6F (HGNC:13933): (lymphocyte antigen 6 family member G6F) The human G6f protein is a type I transmembrane protein belonging to the immunoglobin (Ig) superfamily, which is comprised of cell-surface proteins involved in the immune system and cellular recognition (de Vet et al., 2003 [PubMed 12852788]).[supplied by OMIM, Mar 2008]

LY6G6F-LY6G6D (HGNC:38821): (LY6G6F-LY6G6D readthrough) This locus represents naturally occurring readthrough transcription between the neighboring LY6G6F (lymphocyte antigen 6 family member G6F) and LY6G6D (lymphocyte antigen 6 family member G6D) genes on chromosome 6. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jul 2017]
