Genes affected

ANKS6 (HGNC:26724): (ankyrin repeat and sterile alpha motif domain containing 6) This gene encodes a protein containing multiple ankyrin repeats and a SAM domain. It is thought that this protein may localize to the proximal region of the primary cilium, and may play a role in renal and cardiovascular development. Mutations in this gene have been shown to cause a form of nephronophthisis (NPHP16), a chronic tubulo-interstitial nephritis. [provided by RefSeq, Jul 2015]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 9-98745398-AC-A is Benign according to our data. Variant chr9-98745398-AC-A is described in ClinVar as [Likely_benign]. Clinvar id is 1695470.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00523 (797/152250) while in subpopulation AFR AF= 0.018 (747/41556). AF 95% confidence interval is 0.0169. There are 7 homozygotes in gnomad4. There are 389 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
