Genes affected
RCC2 (HGNC:30297): (regulator of chromosome condensation 2) The protein encoded by this gene is a guanine exchange factor that is active on RalA, a small GTPase. The encoded protein and RalA are both essential for proper kinetochore-microtubule function in early mitosis. This protein has been shown to be a biomarker for colorectal cancer.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.929G>A (p.R310Q) alteration is located in exon 8 (coding exon 7) of the RCC2 gene. This alteration results from a G to A substitution at nucleotide position 929, causing the arginine (R) at amino acid position 310 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
