Genes affected
DSCC1 (HGNC:24453): (DNA replication and sister chromatid cohesion 1) CHTF18 (MIM 613201), CHTF8 (MIM 613202), and DSCC1 are components of an alternative replication factor C (RFC) (see MIM 600404) complex that loads PCNA (MIM 176740) onto DNA during S phase of the cell cycle (Merkle et al., 2003 [PubMed 12766176]; Bermudez et al., 2003 [PubMed 12930902]).[supplied by OMIM, Dec 2009]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.932C>T (p.A311V) alteration is located in exon 8 (coding exon 8) of the DSCC1 gene. This alteration results from a C to T substitution at nucleotide position 932, causing the alanine (A) at amino acid position 311 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
