not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.3007G>A (p.G1003S) alteration is located in exon 16 (coding exon 15) of the ARHGAP20 gene. This alteration results from a G to A substitution at nucleotide position 3007, causing the glycine (G) at amino acid position 1003 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
