Variant 1-9104571-C-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 NM_024980.5(GPR157):c.856G>T(p.Val286Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000143 in 1,613,684 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. V286I) has been classified as Uncertain significance.

Mar 31, 2023

The c.856G>T (p.V286F) alteration is located in exon 4 (coding exon 4) of the GPR157 gene. This alteration results from a G to T substitution at nucleotide position 856, causing the valine (V) at amino acid position 286 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
