Genes affected

APTX (HGNC:15984): (aprataxin) This gene encodes a member of the histidine triad (HIT) superfamily. The encoded protein may play a role in single-stranded DNA repair through its nucleotide-binding activity and its diadenosine polyphosphate hydrolase activity. Mutations in this gene have been associated with ataxia-ocular apraxia. Alternatively spliced transcript variants have been identified for this gene.[provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS2: High Homozygotes in GnomAdExome4 at 2 AR gene
