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]

Ambry Genetics

Feb 26, 2024

The c.870A>C (p.E290D) alteration is located in exon 7 (coding exon 7) of the DSCC1 gene. This alteration results from a A to C substitution at nucleotide position 870, causing the glutamic acid (E) at amino acid position 290 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
