not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.2254G>A (p.V752M) alteration is located in exon 23 (coding exon 23) of the IPO4 gene. This alteration results from a G to A substitution at nucleotide position 2254, causing the valine (V) at amino acid position 752 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
