Variant chr6-89146601-C-T 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.457C>T(p.Pro153Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000519 in 1,444,574 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. P153T) has been classified as Uncertain significance.

Ambry Genetics

Nov 23, 2022

The c.457C>T (p.P153S) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a C to T substitution at nucleotide position 457, causing the proline (P) at amino acid position 153 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
