Genes affected

NUP43 (HGNC:21182): (nucleoporin 43) Bidirectional transport of macromolecules between the cytoplasm and nucleus occurs through nuclear pore complexes (NPCs) embedded in the nuclear envelope. NPCs are composed of subcomplexes, and NUP43 is part of one such subcomplex, Nup107-160 (Loiodice et al., 2004 [PubMed 15146057]).[supplied by OMIM, Mar 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.650G>A (p.R217Q) alteration is located in exon 6 (coding exon 6) of the NUP43 gene. This alteration results from a G to A substitution at nucleotide position 650, causing the arginine (R) at amino acid position 217 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
