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 made for transcript

Verdict is Benign. Variant got -9 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.54).
BP6
Variant 12-40939387-T-C is Benign according to our data. Variant chr12-40939387-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 537200.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-1.1 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000263 (4/152276) while in subpopulation AFR AF= 0.0000963 (4/41558). AF 95% confidence interval is 0.0000324. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
