Genes affected

NUP155 (HGNC:8063): (nucleoporin 155) Nucleoporins are proteins that play an important role in the assembly and functioning of the nuclear pore complex (NPC) which regulates the movement of macromolecules across the nuclear envelope (NE). The protein encoded by this gene plays a role in the fusion of NE vesicles and formation of the double membrane NE. The protein may also be involved in cardiac physiology and may be associated with the pathogenesis of atrial fibrillation. Alternative splicing results in multiple transcript variants of this gene. A pseudogene associated with this gene is located on chromosome 6. [provided by RefSeq, May 2013]

The c.4126A>G (p.I1376V) alteration is located in exon 35 (coding exon 35) of the NUP155 gene. This alteration results from a A to G substitution at nucleotide position 4126, causing the isoleucine (I) at amino acid position 1376 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
