Genes affected

ORC5 (HGNC:8491): (origin recognition complex subunit 5) The origin recognition complex (ORC) is a highly conserved six subunit protein complex essential for the initiation of the DNA replication in eukaryotic cells. Studies in yeast demonstrated that ORC binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors such as Cdc6 and Mcm proteins. The protein encoded by this gene is a subunit of the ORC complex. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Oct 2010]

The c.399G>T (p.M133I) alteration is located in exon 4 (coding exon 4) of the ORC5 gene. This alteration results from a G to T substitution at nucleotide position 399, causing the methionine (M) at amino acid position 133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
