Genes affected

RANGAP1 (HGNC:9854): (Ran GTPase activating protein 1) This gene encodes a protein that associates with the nuclear pore complex and participates in the regulation of nuclear transport. The encoded protein interacts with Ras-related nuclear protein 1 (RAN) and regulates guanosine triphosphate (GTP)-binding and exchange. Alternative splicing results in multiple transcript variants.

The c.1108G>A (p.E370K) alteration is located in exon 11 (coding exon 10) of the RANGAP1 gene. This alteration results from a G to A substitution at nucleotide position 1108, causing the glutamic acid (E) at amino acid position 370 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
