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]

This variant is present in population databases (rs370230003, ExAC 0.01%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with ANKS6-related disease. This sequence change replaces serine with leucine at codon 755 of the ANKS6 protein (p.Ser755Leu). The serine residue is highly conserved and there is a large physicochemical difference between serine and leucine. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.2264C>T (p.S755L) alteration is located in exon 12 (coding exon 12) of the ANKS6 gene. This alteration results from a C to T substitution at nucleotide position 2264, causing the serine (S) at amino acid position 755 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
