Variant 19-38305414-T-C details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_001039672.3(YIF1B):c.883A>G(p.Met295Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,610,576 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 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. M295I) has been classified as Uncertain significance.

The c.883A>G (p.M295V) alteration is located in exon 8 (coding exon 8) of the YIF1B gene. This alteration results from a A to G substitution at nucleotide position 883, causing the methionine (M) at amino acid position 295 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
