Genes affected
KPNA3 (HGNC:6396): (karyopherin subunit alpha 3) The transport of molecules between the nucleus and the cytoplasm in eukaryotic cells is mediated by the nuclear pore complex (NPC), which consists of 60-100 proteins. Small molecules (up to 70 kD) can pass through the nuclear pore by nonselective diffusion while larger molecules are transported by an active process. The protein encoded by this gene belongs to the importin alpha family, and is involved in nuclear protein import. [provided by RefSeq, Jan 2009]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2024The c.696T>A (p.D232E) alteration is located in exon 9 (coding exon 9) of the KPNA3 gene. This alteration results from a T to A substitution at nucleotide position 696, causing the aspartic acid (D) at amino acid position 232 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
