Genes affected

GINS1 (HGNC:28980): (GINS complex subunit 1) The yeast heterotetrameric GINS complex is made up of Sld5 (GINS4; MIM 610611), Psf1, 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]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Sep 14, 2022

The c.16G>T (p.A6S) alteration is located in exon 1 (coding exon 1) of the GINS1 gene. This alteration results from a G to T substitution at nucleotide position 16, causing the alanine (A) at amino acid position 6 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
