Genes affected
ANKRD17 (HGNC:23575): (ankyrin repeat domain 17) The protein encoded by this gene belongs to the family of ankyrin repeat-containing proteins, and contains two distinct arrays of ankyrin repeats in its amino-terminal region, one with 15 ankyrin repeats, and the other with 10 ankyrin repeats. It also contains a nuclear export signal, nuclear localization signal, and a cyclin-binding RXL motif. Localization of this protein to the nucleus has been shown experimentally, and interactions between this protein and cyclin-dependent kinase 2 have been observed. It has been suggested that this protein plays a role in both DNA replication and in both anti-viral and anti-bacterial innate immune pathways. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

The ANKRD17 c.7454A>C (p.His2485Pro) variant is a missense variant. A literature search was performed for the gene, cDNA change and amino acid change. No publications were found based on this search. The p.His2485Pro variant is reported at a frequency of 0.000065 in the European (non-Finnish) population of the Genome Aggregation Database (version 2.1.1), though this is based on one allele in a region of good sequencing coverage, so the variant is presumed to be rare. Based on the limited evidence, the p.His2485Pro variant is classified as a variant of uncertain significance for Chopra-Amiel-Gordon syndrome. -
