Collection Method: clinical testing

The c.537C>G (p.D179E) alteration is located in exon 5 (coding exon 5) of the IPO9 gene. This alteration results from a C to G substitution at nucleotide position 537, causing the aspartic acid (D) at amino acid position 179 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
