Of 313 patients with early-onset or familial MPN, 7 (2.2%) patients had pathogenic/likely pathogenic (P/LP) germline heterozygous loss of function mutations in CHEK2. The presence of CHEK2 variants was associated with a familial history of malignancies and a higher risk of leukemic evolution, reinforcing the hypothesis of CHEK2 variants as tumor predisposing risk allele.

Background: Gastric cancer epidemiology evolved rapidly in the last century, shifting from being one of the main causes of cancer-related death to the sixth in high-income countries.
Methods: We conducted a narrative review on gastric cancer epidemiology. Our review focused on trends of gastric cancer and its relationship with Helicobacter pylori infection; cardia and noncardia gastric cancer risk factors; early onset gastric cancer; second primary cancers in patients with gastric cancer; and implementation of gastric cancer prevention strategies.

Li-Fraumeni syndrome (LFS) is an early-onset cancer syndrome caused by pathogenic germline TP53 variants. Adolescents and young adults (AYAs) with LFS may have challenges navigating new romantic partnerships given the significant effects of LFS on multiple life domains that also affect partners (e.g.

Background: Familial hypercholesterolemia (FH) is a prevalent hereditary disorder, with its monogenic form linked to an elevated risk of early-onset ischemic heart disease. Evaluating the prevalence and penetrance of pathogenic and likely pathogenic variants associated with this disorder would provide valuable information supporting routine FH screening of the general population. Such informed screening would facilitate early identification of at-risk individuals, enabling timely intervention and management.

Fumarate hydratase (FH) deficient uterine leiomyomas account for only 0.4 % of all uterine leiomyomas. They have some unique histological characteristics and can be linked to renal cell carcinoma (HLRCC) syndrome and hereditary leiomyomatosis.
