Genes affected
TGM6 (HGNC:16255): (transglutaminase 6) The protein encoded by this gene belongs to the transglutaminase superfamily. It catalyzes the cross-linking of proteins and the conjugation of polyamines to proteins. Mutations in this gene are associated with spinocerebellar ataxia type 35 (SCA35). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

BP6
Variant 20-2430472-T-A is Benign according to our data. Variant chr20-2430472-T-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 448672.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.
BS2
High AC in GnomAd4 at 61 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
