Ambry Genetics

Apr 17, 2023

The c.375A>G (p.I125M) alteration is located in exon 3 (coding exon 2) of the TMEM117 gene. This alteration results from a A to G substitution at nucleotide position 375, causing the isoleucine (I) at amino acid position 125 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
