The c.3161A>T (p.Q1054L) alteration is located in exon 30 (coding exon 30) of the IPO4 gene. This alteration results from a A to T substitution at nucleotide position 3161, causing the glutamine (Q) at amino acid position 1054 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
