The c.2152C>T (p.H718Y) alteration is located in exon 22 (coding exon 22) of the IPO4 gene. This alteration results from a C to T substitution at nucleotide position 2152, causing the histidine (H) at amino acid position 718 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
