Variant chr8-142315086-G-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_145003.5(TSNARE1):c.991C>A(p.Arg331Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000479 in 1,461,690 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R331L) has been classified as Uncertain significance.

The c.991C>A (p.R331S) alteration is located in exon 8 (coding exon 7) of the TSNARE1 gene. This alteration results from a C to A substitution at nucleotide position 991, causing the arginine (R) at amino acid position 331 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
