Genes affected

NUP133 (HGNC:18016): (nucleoporin 133) The nuclear envelope creates distinct nuclear and cytoplasmic compartments in eukaryotic cells. It consists of two concentric membranes perforated by nuclear pores, large protein complexes that form aqueous channels to regulate the flow of macromolecules between the nucleus and the cytoplasm. These complexes are composed of at least 100 different polypeptide subunits, many of which belong to the nucleoporin family. The nucleoporin protein encoded by this gene displays evolutionarily conserved interactions with other nucleoporins. This protein, which localizes to both sides of the nuclear pore complex at interphase, remains associated with the complex during mitosis and is targeted at early stages to the reforming nuclear envelope. This protein also localizes to kinetochores of mitotic cells. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.124G>A (p.A42T) alteration is located in exon 1 (coding exon 1) of the NUP133 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the alanine (A) at amino acid position 42 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
