Genes affected

GINS3 (HGNC:25851): (GINS complex subunit 3) This gene encodes a protein subunit of the GINS heterotetrameric complex, which is essential for the initiation of DNA replication and replisome progression in eukaryotes. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

GINS3 Gene-Disease associations (from GenCC):

• Meier-Gorlin syndrome
