Genes affected

MDC1 (HGNC:21163): (mediator of DNA damage checkpoint 1) The protein encoded by this gene contains an N-terminal forkhead domain, two BRCA1 C-terminal (BRCT) motifs and a central domain with 13 repetitions of an approximately 41-amino acid sequence. The encoded protein is required to activate the intra-S phase and G2/M phase cell cycle checkpoints in response to DNA damage. This nuclear protein interacts with phosphorylated histone H2AX near sites of DNA double-strand breaks through its BRCT motifs, and facilitates recruitment of the ATM kinase and meiotic recombination 11 protein complex to DNA damage foci.

The c.5293G>A (p.E1765K) alteration is located in exon 10 (coding exon 9) of the MDC1 gene. This alteration results from a G to A substitution at nucleotide position 5293, causing the glutamic acid (E) at amino acid position 1765 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
