Genes affected

INVS (HGNC:17870): (inversin) This gene encodes a protein containing multiple ankyrin domains and two IQ calmodulin-binding domains. The encoded protein may function in renal tubular development and function, and in left-right axis determination. This protein interacts with nephrocystin and infers a connection between primary cilia function and left-right axis determination. A similar protein in mice interacts with calmodulin. Mutations in this gene have been associated with nephronophthisis type 2. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, May 2012]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.008226305).

BP6

Variant 9-100284460-A-G is Benign according to our data. Variant chr9-100284460-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 194250.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000696 (106/152358) while in subpopulation AFR AF = 0.00245 (102/41596). AF 95% confidence interval is 0.00207. There are 0 homozygotes in GnomAd4. There are 47 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
