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 -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.48).
BP6
Variant 12-40918691-T-C is Benign according to our data. Variant chr12-40918691-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 383252.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=2.17 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000322 (49/152142) while in subpopulation NFE AF= 0.000573 (39/68006). AF 95% confidence interval is 0.000431. There are 0 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
