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 Benign. Variant got -10 ACMG points.

• BP6: Variant 9-32986032-T-TAAAAAAAAACAAA is Benign according to our data. Variant chr9-32986032-T-TAAAAAAAAACAAA is described in ClinVar as [Likely_benign]. Clinvar id is 2112401.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000855 (614/718470) while in subpopulation EAS AF= 0.00364 (89/24424). AF 95% confidence interval is 0.00303. There are 7 homozygotes in gnomad4_exome. There are 330 alleles in male gnomad4_exome subpopulation. Median coverage is 10. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 7 AR gene
