Genes affected

TOR1A (HGNC:3098): (torsin family 1 member A) The protein encoded by this gene is a member of the AAA family of adenosine triphosphatases (ATPases), is related to the Clp protease/heat shock family and is expressed prominently in the substantia nigra pars compacta. Mutations in this gene result in the autosomal dominant disorder, torsion dystonia 1. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 9-129813556-A-AC is Benign according to our data. Variant chr9-129813556-A-AC is described in ClinVar as [Likely_benign]. Clinvar id is 365222.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00775 (1176/151738) while in subpopulation AFR AF= 0.0265 (1096/41312). AF 95% confidence interval is 0.0252. There are 13 homozygotes in gnomad4. There are 572 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 13 AD,AR gene
