Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001003693.3(LY6G6F):​c.416C>G​(p.Ser139Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,190 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S139Y) has been classified as Uncertain significance.

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]

ENSG00000204422 (HGNC:):
