Genes affected

DRC1 (HGNC:24245): (dynein regulatory complex subunit 1) This gene encodes a central component of the nexin-dynein complex (N-DRC), which regulates the assembly of ciliary dynein. Mutations in this gene can cause ciliary dyskinesia. [provided by RefSeq, Aug 2015]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PP5

Variant 2-26421396-C-T is Pathogenic according to our data. Variant chr2-26421396-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 55840.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000629 (919/1460280) while in subpopulation NFE AF = 0.000771 (857/1110948). AF 95% confidence interval is 0.000728. There are 2 homozygotes in GnomAdExome4. There are 449 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High Homozygotes in GnomAdExome4 at 2 AR,AD gene
