Ambry Genetics

May 04, 2022

The c.3002T>C (p.I1001T) alteration is located in exon 28 (coding exon 28) of the IPO4 gene. This alteration results from a T to C substitution at nucleotide position 3002, causing the isoleucine (I) at amino acid position 1001 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
