Ambry Genetics

Nov 30, 2022

The c.203T>C (p.I68T) alteration is located in exon 3 (coding exon 3) of the TMEM147 gene. This alteration results from a T to C substitution at nucleotide position 203, causing the isoleucine (I) at amino acid position 68 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
