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

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 9-100126595-C-T is Benign according to our data. Variant chr9-100126595-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 260411.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0339 (5154/152228) while in subpopulation NFE AF = 0.0466 (3172/68018). AF 95% confidence interval is 0.0453. There are 155 homozygotes in GnomAd4. There are 2612 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 155 AR gene
