Variant 6-89146295-C-G 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_001010853.3(PM20D2):c.151C>G(p.Leu51Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000215 in 1,581,092 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. L51Q) has been classified as Uncertain significance.

Ambry Genetics

Dec 16, 2023

The c.151C>G (p.L51V) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a C to G substitution at nucleotide position 151, causing the leucine (L) at amino acid position 51 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
