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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in the ANKRD17 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 11 curated pathogenic missense variants (we use a threshold of 10). The gene has 15 curated benign missense variants. Gene score misZ: 5.3588 (above the threshold of 3.09). Trascript score misZ: 6.9945 (above the threshold of 3.09). GenCC associations: The gene is linked to syndromic intellectual disability, Chopra-Amiel-Gordon syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.073758036).

BS2

High AC in GnomAdExome4 at 17 AD gene.

The c.7403A>G (p.N2468S) alteration is located in exon 31 (coding exon 31) of the ANKRD17 gene. This alteration results from a A to G substitution at nucleotide position 7403, causing the asparagine (N) at amino acid position 2468 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
