Variant chr6-61732697-G-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The ENST00000281156.5(KHDRBS2):c.878C>T(p.Ala293Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000151 in 1,605,580 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 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. A293T) has been classified as Uncertain significance.

The c.878C>T (p.A293V) alteration is located in exon 7 (coding exon 7) of the KHDRBS2 gene. This alteration results from a C to T substitution at nucleotide position 878, causing the alanine (A) at amino acid position 293 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
