Ambry Genetics

Dec 14, 2023

The c.188T>C (p.I63T) alteration is located in exon 3 (coding exon 3) of the RIT2 gene. This alteration results from a T to C substitution at nucleotide position 188, causing the isoleucine (I) at amino acid position 63 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
