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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.106A>G (p.M36V) alteration is located in exon 2 (coding exon 2) of the GINS1 gene. This alteration results from a A to G substitution at nucleotide position 106, causing the methionine (M) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 24, 2021In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals with GINS1-related conditions. This variant is present in population databases (rs190474037, ExAC 0.01%). This sequence change replaces methionine with valine at codon 36 of the GINS1 protein (p.Met36Val). The methionine residue is moderately conserved and there is a small physicochemical difference between methionine and valine. -
