Ambry Genetics

Dec 17, 2023

The c.1432A>G (p.I478V) alteration is located in exon 12 (coding exon 9) of the SCMH1 gene. This alteration results from a A to G substitution at nucleotide position 1432, causing the isoleucine (I) at amino acid position 478 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
