Genes affected

KANK1 (HGNC:19309): (KN motif and ankyrin repeat domains 1) The protein encoded by this gene belongs to the Kank family of proteins, which contain multiple ankyrin repeat domains. This family member functions in cytoskeleton formation by regulating actin polymerization. This gene is a candidate tumor suppressor for renal cell carcinoma. Mutations in this gene cause cerebral palsy spastic quadriplegic type 2, a central nervous system development disorder. A t(5;9) translocation results in fusion of the platelet-derived growth factor receptor beta gene (PDGFRB) on chromosome 5 with this gene in a myeloproliferative neoplasm featuring severe thrombocythemia. Alternative splicing of this gene results in multiple transcript variants. A related pseudogene has been identified on chromosome 20. [provided by RefSeq, Dec 2014]

A KANK1 c.1801G>A (p.Glu601Lys) variant was identified. This variant, to our knowledge, has not been reported in the medical literature. It is observed on 225/282,634 alleles in the general population (gnomAD v.2.1.1). This variant has been reported in the ClinVar database as a germline variant and classified as likely benign by two submitters (ClinVar ID: 445518). Computational predictors are uncertain as to the impact of this variant on CUBN function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -
