Ambry Genetics

Jan 23, 2024

The c.700A>G (p.M234V) alteration is located in exon 10 (coding exon 9) of the SUPT20H gene. This alteration results from a A to G substitution at nucleotide position 700, causing the methionine (M) at amino acid position 234 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
