Genes affected
KANK2 (HGNC:29300): (KN motif and ankyrin repeat domains 2) This gene encodes a member of the KN motif and ankyrin repeat domains (KANK) family of proteins, which play a role in cytoskeletal formation by regulating actin polymerization. The encoded protein functions in the sequestration of steroid receptor coactivators and possibly other proteins. Mutations in this gene are associated with impaired kidney podocyte function and nephrotic syndrome, and keratoderma and woolly hair. [provided by RefSeq, Jul 2016]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 17, 2023 | The c.2506C>T (p.R836C) alteration is located in exon 10 (coding exon 10) of the KANK2 gene. This alteration results from a C to T substitution at nucleotide position 2506, causing the arginine (R) at amino acid position 836 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
