Ambry Genetics

Apr 12, 2024

The c.1001G>C (p.W334S) alteration is located in exon 9 (coding exon 9) of the ARHGEF33 gene. This alteration results from a G to C substitution at nucleotide position 1001, causing the tryptophan (W) at amino acid position 334 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
