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 was made for transcript

Our verdict: Likely_benign. The variant received -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 VariationId is 448672.

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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1705T>A (p.Y569N) alteration is located in exon 11 (coding exon 11) of the TGM6 gene. This alteration results from a T to A substitution at nucleotide position 1705, causing the tyrosine (Y) at amino acid position 569 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
