Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.2851C>T (p.R951W) alteration is located in exon 27 (coding exon 27) of the IPO4 gene. This alteration results from a C to T substitution at nucleotide position 2851, causing the arginine (R) at amino acid position 951 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
