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]

Combined immunodeficiency due to GINS1 deficiency Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingClinical Genomics Laboratory, Stanford MedicineAug 30, 2019The p.Glu18Glnfs*24 variant in the GINS1 gene has not been previously reported in association with disease. This variant was absent from large population databases, including the Genome Aggregation Database (http://gnomad.broadinstitute.org/). The p.Glu18Glnfs*24 variant causes a shift in the protein reading frame, leading to a premature termination codon 24 amino acids downstream. It is currently unknown if GINS1 loss of function is associated with disease. These data were assessed using the ACMG/AMP variant interpretation guidelines. In summary, the significance of the p.Glu18Glnfs*24 variant is uncertain. Additional information is needed to resolve the significance of this variant. [ACMG evidence codes used: PM2] -
