Genes affected
CNTN1 (HGNC:2171): (contactin 1) 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. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.19242918).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000153 (224/1461106) while in subpopulation NFE AF = 0.000189 (210/1111424). AF 95% confidence interval is 0.000168. There are 0 homozygotes in GnomAdExome4. There are 113 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
