Genes affected

CNTN5 (HGNC:2175): (contactin 5) The protein encoded by this gene is a member of the immunoglobulin superfamily, and contactin family, which mediate cell surface interactions during nervous system development. This protein 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. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009718627).

BP6

Variant 11-100061278-A-T is Benign according to our data. Variant chr11-100061278-A-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 446039.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.00104 (1523/1461362) while in subpopulation AMR AF = 0.0178 (798/44716). AF 95% confidence interval is 0.0168. There are 14 homozygotes in GnomAdExome4. There are 698 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
