Ambry Genetics

Jun 06, 2022

The c.20G>C (p.C7S) alteration is located in exon 1 (coding exon 1) of the MT1X gene. This alteration results from a G to C substitution at nucleotide position 20, causing the cysteine (C) at amino acid position 7 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
