Genes affected

RCC1 (HGNC:1913): (regulator of chromosome condensation 1) Enables several functions, including guanyl-nucleotide exchange factor activity; nucleosomal DNA binding activity; and protein heterodimerization activity. Involved in several processes, including G1/S transition of mitotic cell cycle; regulation of mitotic nuclear division; and spindle organization. Located in chromatin; cytoplasm; and nucleus. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1031G>A (p.G344E) alteration is located in exon 10 (coding exon 9) of the RCC1 gene. This alteration results from a G to A substitution at nucleotide position 1031, causing the glycine (G) at amino acid position 344 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
