The c.2951C>T (p.A984V) alteration is located in exon 28 (coding exon 28) of the IPO4 gene. This alteration results from a C to T substitution at nucleotide position 2951, causing the alanine (A) at amino acid position 984 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
