Description
This variant disrupts a canonical splice-donor site and interferes with normal CHEK2 mRNA splicing. In the published literature, the variant has been reported in individuals and families with hereditary cancer (PMIDs: 28779002 (2017), 25583358 (2015), 24713400 (2014), 21876083 (2011), and 15492928 (2004)). The frequency of this variant in the general population, 0.00052 (13/25122 chromosomes, http://gnomad.broadinstitute.org), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic.

Description
This variation occurs one base after exon 3 of the CHEK2 gene in a position highly conserved in the human and other genomes that is crucial for mRNA processing. This is expected to result in incorrect splicing and likely results in an absent or disrupted protein product. This variant has been reported in literature in individuals with increased risk for breast, prostate and other cancers (PMID:15492928, PMID: 19030985, PMID:12533788, PMID: 15492928). This variant is also known as IVS2+1G>A in the literature. The mutation database ClinVar contains entries for this variant (Variation ID: 128075). Algorithms developed to predict the effect of single base changes on mRNA splicing suggest that this variant may alter this cellular process. Moreover, experimental studies support the pathogenic effect of this variant through in mRNA splicing (PMID: 12533788).

Description
The CHEK2 c.444+1G>A variant (rs121908698), also known as IVS2+1G>A, is reported in numerous individuals with familial breast cancer and prostate cancer, and is considered to be one of three CHEK2 founder variants in the Polish population (Bak 2014, Cybulski 2004, Cybulski 2006, Dong 2003). Functional analysis showed that this variant results in a 4-bp insertion due to abnormal splicing and creates a premature termination codon eliminating part of the FHA domain and the entire kinase activation domain of CHEK2 (Dong 2003). This variant is reported in ClinVar (Variation ID: 128075). It is observed in the general population with an overall allele frequency of 0.01% (40/282678 alleles) in the Genome Aggregation Database. Based on available information, this variant is considered to be pathogenic. References: Bak A et al.
