Genes affected

GINS4 (HGNC:28226): (GINS complex subunit 4) The yeast heterotetrameric GINS complex is made up of Sld5, Psf1 (GINS1; MIM 610608), Psf2 (GINS2; MIM 610609), and Psf3 (GINS3; MIM 610610). The formation of the GINS 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.656C>T (p.A219V) alteration is located in exon 8 (coding exon 7) of the GINS4 gene. This alteration results from a C to T substitution at nucleotide position 656, causing the alanine (A) at amino acid position 219 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
