Genetic Variant SYNE3:p.Arg961His (chr14-95417872-C-T) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_152592.6(SYNE3):c.2882G>A(p.Arg961His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000285 in 1,614,050 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R961C) has been classified as Uncertain significance.

The c.2882G>A (p.R961H) alteration is located in exon 17 (coding exon 17) of the SYNE3 gene. This alteration results from a G to A substitution at nucleotide position 2882, causing the arginine (R) at amino acid position 961 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
