dbSNP rs201450079: CNTN6:p.Gly54Ser (chr3-1220791-G-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_001289080.2(CNTN6):c.160G>A(p.Gly54Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000808 in 1,609,456 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. G54C) has been classified as Uncertain significance.

Genes affected

CNTN6 (HGNC:2176): (contactin 6) The protein encoded by this gene is a member of the immunoglobulin superfamily. It is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
