Ambry Genetics

Feb 07, 2023

The c.710T>C (p.M237T) alteration is located in exon 6 (coding exon 6) of the ARHGEF38 gene. This alteration results from a T to C substitution at nucleotide position 710, causing the methionine (M) at amino acid position 237 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
