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.637G>A (p.D213N) alteration is located in exon 7 (coding exon 6) of the RCC1 gene. This alteration results from a G to A substitution at nucleotide position 637, causing the aspartic acid (D) at amino acid position 213 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
