Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 0P and 17B. BP4_StrongBP6_Very_StrongBS1BS2_Supporting

The NM_198994.3(TGM6):c.1171G>A(p.Val391Met) variant causes a missense change. The variant allele was found at a frequency of 0.000328 in 1,614,162 control chromosomes in the GnomAD database, including 8 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V391L) has been classified as Uncertain significance.

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: Benign. The variant received -17 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.02161333).

BP6

Variant 20-2403658-G-A is Benign according to our data. Variant chr20-2403658-G-A is described in ClinVar as Benign. ClinVar VariationId is 337923.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000374 (57/152290) while in subpopulation EAS AF = 0.00869 (45/5180). AF 95% confidence interval is 0.00667. There are 0 homozygotes in GnomAd4. There are 36 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 57 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
