Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.2293C>T (p.R765C) alteration is located in exon 23 (coding exon 23) of the IPO4 gene. This alteration results from a C to T substitution at nucleotide position 2293, causing the arginine (R) at amino acid position 765 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
