RPS20 pathogenic variants are very rare with only five reported cases in the literature. We report in this work the retrospective germline analysis of RPS20 for 1035 consecutive patients with a personal and/or familial history suggestive of hereditary predisposition to CRC. Within this series, a pathogenic variant in known CRC genes was found in 15% of cases and we describe one RPS20 loss-of-function variant (NM_001146227.1:c.115_116del, p.(Leu39Aspfs*33)). This frameshift is the first reported de novo variant in CRC, it was identified in in a female patient diagnosed with rectal cancer at the age of 35, 11 adenomatous polyps in 5 years and breast cancer at the age of 43. RPS20 has an intriguing role in oncogenesis, acting as an oncogene or tumour suppressor depending on the context, and is also involved in Diamond-Blackfan anemia via gain of function or dominant negative variants. This is therefore a complex gene for genetic counselling and, given the rarity of RPS20 pathogenic variants, we emphasise the need to collect data to clarify the phenotypic spectrum of RPS20-associated cancers and thus improve management.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"22"},"PeriodicalIF":1.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report details a 51-year-old male diagnosed with MDS with excess blasts-1 (MDS-EB1), who harbored a rare combination of pathogenic germline variants in RUNX1 and a novel potentially pathogenic variant in DDX41 variant, alongside a somatic DDX41 mutation. The coexistence of these germline variants highlights the genetic complexity underlying hereditary myeloid neoplasms and reinforces the necessity of comprehensive genomic testing to ensure accurate diagnosis and informed clinical management. The interplay between RUNX1 and DDX41 variants may drive leukemogenesis, with the germline RUNX1 variant potentially fostering a cellular environment that enables the acquisition of somatic DDX41 mutations, leading to hematological malignancies. Conversely, the germline DDX41 variant may disrupt hematopoiesis and, when combined with RUNX1 dysfunction, contribute to disease progression. This case underscores the importance of screening germline variants in patients with myeloid neoplasms. It emphasizes the need to confirm the origin of these variants in non-hematopoietic tissues, such as fibroblasts (gold standard), to avoid misinterpretation caused by clonal hematopoiesis. Further research is warranted to elucidate the molecular mechanisms driving the interaction between RUNX1 and DDX41 variants and their collective impact on disease progression, treatment outcomes, and familial risk.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"20"},"PeriodicalIF":1.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143073200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lifelong surveillance protocols are essential to detect and prevent adverse developments. However, limited data exist regarding the long-term feasibility of such programs. This study aims to evaluate the compliance with a surveillance program for patients with familial adenomatous polyposis. The study collated data from all patients who underwent surgery between January 1981 and December 1993, excluding non-French residents. Recorded characteristics included medical history, follow-up results, the indications for operations or other procedures, outcomes of these interventions, and patient status at the end of the follow-up period. One hundred and sixty-four patients were enrolled, comprising 86 females (52.4%). The median age at the time of colorectal resection was 29.6 years [10-67]. Thirty-six (22.0%) were diagnosed with cancer at the time of their surgery. Fifty-eight patients (35.3%) passed away at a median age of 52 years [18-95]. During the follow-up period, 47 patients developed duodenal or reservoir adenomas requiring invasive procedures, or desmoid tumors necessitating treatment. After a possible 30 years of follow-up, 49 survivors (46.2%) are still under observation, while 57 (53.8%) have been lost to follow-up. After 30 years of follow-up, the survival rate was 74.2% for patients who remained under observation, but only 58.2% for those lost to follow-up. Long-term follow-up of patients with familial adenomatous polyposis is associated with a high rate of loss to follow-up. However, those who remain under observation maintain an excellent prognosis. Understanding the reasons for loss to follow-up is challenging but may help in reducing this high attrition rate.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"19"},"PeriodicalIF":1.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143073715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Li-Fraumeni syndrome (LFS), an autosomal dominant cancer predisposition syndrome, is caused by a germline variant of the tumor suppressor gene TP53. Here, we report the case of a 20-year-old woman with LFS who developed a PEComa of the liver. She was suspected to have LFS because she had developed osteosarcoma (OS) of the femur along with a concurrent transitional liver cell tumor in the right liver lobe at the age of 8 years. She also tested positive for the germline TP53 missense variant c.722 C > T (p.Ser241Phe). She concurrently experienced recurrence of OS and a new-onset liver tumor at the age of 20 years. Thereafter, microwave ablation was performed for the liver tumor because the Magnetic resonance imaging features suggested that the tumor was a hepatocellular carcinoma. Post-ablation biopsy showed that the tumor cells were spindle-shaped and possessed eosinophilic cytoplasm. Immunohistochemistry revealed that the tumor cells expressed HMB45 and focal alpha-smooth muscle actin. Labeling for S100 protein and cytokeratin-AE1/AE3 yielded negative results. Therefore, a diagnosis of PEComa of the liver was made. Among the ten PEComas reported in patients with Li-Fraumeni syndrome so far, all PEComas except the current case were surgically resected, and no cases of recurrence were documented in the follow-up period. Six of the ten PEComas were located in the liver. We think that the possibility of PEComa should be considered when a liver tumor develops in patients with LFS.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"18"},"PeriodicalIF":1.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143037786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the lifelong risk of developing NEN requires special considerations to avoid excessive surgeries and to minimize damage to the patient's function and well-being.

It is caused by heterozygous variants in the DNA mismatch repair genes- MLH1, MSH2, MSH6 and PMS2, with the majority detected in MLH1 and MSH2. Recurrently observed LS-associated variants in apparently unrelated individuals have either arisen de novo in different families due to mutation hotspots or are inherited from a common ancestor (founder) that lived several generations back. Testing for founder variants can facilitate molecular diagnosis of LS more efficiently and cost effectively than screening for all possible variants in the MMR genes. Here, we report a study of the missense variant c.306G > T in the MLH1 gene, the first potential founder variant identified in LS patients of Indian ethnicity. Haplotype analysis consisting of 25 LS carriers with the MLH1 c.306G > T variant and 100 healthy controls confirmed a shared haplotype in cases spanning a 27.8 kb region encompassing the c.306G > T variant (𝝌2 = 96.418; p = < 0.0001). Age of variant analysis suggests the variant to have arisen in the population approximately 800 years (95% CI: 670-934 years) ago.
