Genes affected

GINS2 (HGNC:24575): (GINS complex subunit 2) The yeast heterotetrameric GINS complex is made up of Sld5 (GINS4; MIM 610611), Psf1 (GINS1; MIM 610608), Psf2, and Psf3 (GINS3; MIM 610610). The formation of this complex is essential for the initiation of DNA replication in yeast and Xenopus egg extracts (Ueno et al., 2005 [PubMed 16287864]). See GINS1 for additional information about the GINS complex.[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.428C>G (p.A143G) alteration is located in exon 4 (coding exon 4) of the GINS2 gene. This alteration results from a C to G substitution at nucleotide position 428, causing the alanine (A) at amino acid position 143 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
