Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_024605.4(ARHGAP10):​c.664A>G​(p.Asn222Asp) variant causes a missense change. The variant allele was found at a frequency of 0.00000547 in 1,461,428 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. N222S) has been classified as Uncertain significance.

Ambry Genetics

Apr 19, 2023

The c.664A>G (p.N222D) alteration is located in exon 7 (coding exon 7) of the ARHGAP10 gene. This alteration results from a A to G substitution at nucleotide position 664, causing the asparagine (N) at amino acid position 222 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
