Ambry Genetics

Jan 17, 2023

The c.1050A>G (p.I350M) alteration is located in exon 10 (coding exon 10) of the ITFG1 gene. This alteration results from a A to G substitution at nucleotide position 1050, causing the isoleucine (I) at amino acid position 350 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
