Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP4

The ENST00000263674.4(ARHGEF17):​c.340G>T​(p.Ala114Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. 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. A114E) has been classified as Uncertain significance.

Ambry Genetics

Mar 19, 2024

The c.340G>T (p.A114S) alteration is located in exon 1 (coding exon 1) of the ARHGEF17 gene. This alteration results from a G to T substitution at nucleotide position 340, causing the alanine (A) at amino acid position 114 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
