Variant chr12-29451489-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001353179.2(OVCH1):c.2716C>G(p.Leu906Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,102 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/17 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. L906P) has been classified as Uncertain significance.

The c.2611C>G (p.L871V) alteration is located in exon 22 (coding exon 22) of the OVCH1 gene. This alteration results from a C to G substitution at nucleotide position 2611, causing the leucine (L) at amino acid position 871 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
