Incidental genetic finding

INTRODUCTION AND IMPORTANCE: NUT carcinoma of the thorax is an extremely rare neoplasm characterized by a translocation between the NUT M1 gene and members of the bromodomain genetic family. Due to the rarity of the neoplasm, standardized treatment guidelines have not yet been established. Several chemotherapeutic agents have been used with limited success, due to the rapid development of resistance to treatment. Pembrolizumab, an anti-programmed-death-1 antibody, has become increasingly used in non-small-cell lung carcinomas...

Non-paternity (NP) is a challenging dilemma faced by genetics providers and there is little consensus on whether this finding should be disclosed. Discussions in the literature are highly theoretical, with limited research regarding how disclosure decisions are enacted in practice. We explored genetic counselors' (GCs) clinical experiences with NP to understand if, how, and why this finding is communicated. Our semi-structured interviews with genetic counselors in the United States and Canada were analyzed using reflexive thematic analysis to analyze data inductively, describe themes, and present a meaningful interpretation of the data...

Penile torsion is the abnormal three-dimensional twisting of penile corporal bodies. It can be classified as mild, moderate, or severe, depending on the degree of torsion. Severe penile torsion (>90°) is a very rare condition, with an estimated incidence of 0.4%-1% among all penile torsion cases. Our patient was a 37-year-old man complaining of a 2-year history of lower urinary tract symptoms. These symptoms appeared after the patient sustained an iatrogenic injury during Foley catheter insertion. Physical examination incidentally revealed an obvious counterclockwise penile rotation of 180°...

Microscopic haematuria is a common incidental finding in childhood which often resolves on its own. However, it can be an early marker of genetic kidney disease. It is best practice to repeat testing to ensure resolution. Using data from the electronic medical record, we set out to find children without follow up, offer testing, and look for genetic kidney disease.

Hepatocellular carcinoma (HCC) is the most frequently found primary malignancy of the liver, showing an accelerated upward trend over the past few years and exhibiting an increasing relationship with metabolic syndrome, obesity, dyslipidemia and type 2 diabetes mellitus. The connection between these risk factors and the occurrence of HCC is represented by the occurrence of non-alcoholic fatty liver disease (NAFLD) which later, based on genetic predisposition and various triggers (including the presence of chronic inflammation and changes in the intestinal microbiome), may evolve into HCC...

Population-based biobanking is an essential element of medical research that has grown substantially over the last two decades, and many countries are currently pursuing large national biobanking initiatives. The rise of individual biobanks is paralleled by various networking activities in the field at both the national and international level, such as BBMRI-ERIC in the EU. A significant contribution to population-based biobanking comes from large cohort studies and national repositories, including the United Kingdom Biobank (UKBB), the CONSTANCES project in France, the German National Cohort (NAKO), LifeLines in the Netherlands, FinnGen in Finland, and the All of Us project in the U...

Essential thrombocythemia (ET) is a myeloproliferative neoplasm variant characterized by excessive production of platelets. Since the most common cause of mortality and morbidity in ET patients is thrombosis, the excessive production of platelets may cause thrombotic events. However, little is known about the function of platelets in ET. We report a female patient who presented as asymptomatic, without a remarkable medical history, and ET was diagnosed after an incidental finding of moderate thrombocytosis...

We provide the incidental necropsy findings associated with anisakid nematode infections of black noddy terns, Anous minutus Boie, 1844 (Charadriiformes: Laridae), from offshore islands in the southern Great Barrier Reef, Queensland, Australia. Specimens collected from the proventriculi were identified morphologically as Contracaecum magnipapillatum Chapin, 1925 (Rhabditida: Anisakidae), using light and scanning electron microscopy (SEM). The entire nuclear ribosomal DNA internal transcribed spacer (ITS) region (ITS1-5...

BACKGROUND: Situs inversus totalis (SIT) may be an incidental finding in asymptomatic children. Patients may not understand the implications of this condition and the importance of relaying the diagnosis to their healthcare providers. CASE SUMMARY: We report an asymptomatic seventeen-year-old adolescent with previously-diagnosed SIT who presented for a routine well-child visit. During history taking, he denied any past medical conditions, including cardiovascular conditions...

BACKGROUND: Prostate cancer is often considered a disease of older men and this indeed fits with its peak incidence between 65-79 years of age. Reports of prostate cancer in men younger than 40 years of age and the outcomes of this age group following treatment are few in the literature. Here, we present the case of an unusual diagnosis of high grade prostate cancer in a very young man and outline early outcomes following treatment with robotic-assisted radical prostatectomy. CASE PRESENTATION: A 35-year-old male, intermittently taking finasteride for hair loss, was found to have an elevated prostate-specific antigen (PSA) of 12...

Endocrine cells responsible for hormone secretion are found in virtually every organ system. The diverse neoplasms arising from endocrine cells in the female reproductive tract are not well recognized as a distinct component of endocrine oncology. Here, we integrate cellular origins with native anatomical residence to help classify neoplasms of this system. The neoplasms include steroidogenic tumors that arise usually in ovarian stroma, neuroendocrine neoplasms that can arise from normal neuroendocrine cells throughout the female reproductive tract or in ovarian germ cell tumors, and thyroid follicular cell proliferations that are exclusively a component of an ovarian teratoma and may be malignant...

Despite the commercialization of Next generation sequencing (NGS) gene testing, only a few studies have addressed the various ethical and legal problems associated with NGS testing in Korea Here, we reviewed the normative issues that emerged at each stage of the wet analysis and bioinformatics analysis of NGS gene testing. In particular, it was in mind to apply various international guidelines and the principles of bioethics to actual clinical practice. Considering the characteristics of NGS testing, wet analysis of additional testing can be justified if presumptive consent is recognized...

OBJECTIVES: Cation exchange high-performance liquid chromatography (HPLC) is one of the techniques available for determining glycated hemoglobin (HbA1c ) and also the method of choice for structural hemoglobinopathies screening. The objective of this case is to show how in a routine HbA1c test it is possible to incidentally find a hemoglobinopathy. CASE PRESENTATION: In a routine blood analysis, an abnormal value for the hemoglobin A2 (HbA2 ) was obtained during the study of HbA1c with HPLC on the ADAMS™ A1c HA-8180T...

Trio exome sequencing was performed on a fetus with bilateral mesomelia of the lower limbs with significant angulation of the tibial bones, micrognathia and hypertelorism detected on ultrasound scan at 19 + 0 weeks gestation. The couple is consanguineous. A homozygous pathogenic frameshift variant in the SMOC1 gene (c.339_340del p.(Phe114Cysfs*40)) was detected and both parents were shown to be heterozygous. Pathogenic variants in the SMOC1 gene are associated with microphthalmia with limb anomalies which multidisciplinary team discussion determined to be causal of the scan anomalies detected...

Following hematopoietic cell transplantation, recipients are subjected to extensive genetic testing to monitor the efficacy of the transplant and identify relapsing malignant disease. This testing increasingly includes the use of large gene panels which may lead to incidental identification of genetic and molecular information of potential donor origin. Deciphering whether variants are of donor origin, and if so, whether there are clinical implications for the donor, can prove challenging. In response to queries from donor registries and transplant centers regarding best practice in managing donors when genetic mutations of potential donor origin are identified, the Medical Working Group of the World Marrow Donor Association established an expert group to review available evidence and to develop a framework to aid decision-making...

In this case report, we aim to illustrate a presentation of familial exudative vitreoretinopathy (FEVR) that closely resembles incontinentia pigmenti (IP) and the role of genetic testing that is of no cost to the patient in providing the correct diagnosis. We present a case of an 11-year-old female-to-male transgender patient with a history of hypodontia and skin hypopigmentation who was incidentally found to have a retinal lesion on ultra-widefield fundus imaging during routine screening. Ultra-widefield fluorescein angiography confirmed bilateral peripheral ischemic retinopathy that was successfully treated with laser...

Hereditary predisposition to cancer affects about 3-5% of renal cancers. Testing criteria have been proposed in France for genetic testing of non-syndromic renal cancer. Our study explores the detection rates associated with our testing criteria. Using a comprehensive gene panel including 8 genes related to renal cancer and 50 genes related to hereditary predisposition to other cancers, we evaluated the detection rate of pathogenic variants in a cohort of 83 patients with suspected renal cancer predisposition...

The rising utilization of circulating tumor DNA (ctDNA) assays in Precision Oncology may incidentally detect genetic material from secondary sources. It is important that such findings are recognized and properly leveraged for both diagnosis and monitoring of response to treatment. Here, we report a patient in whom serial cell-free DNA (cfDNA) monitoring for his known prostate adenocarcinoma uncovered the emergence of an unexpected FGFR3-TACC3 gene fusion, a BRCA1 frameshift mutation, and other molecular abnormalities...

OBJECTIVES: Alpha-mannosidosis is a rare genetic lysosomal storage condition leading to the systemic buildup of oligomannoside. Clinical presentation and associated conditions, as well as the full extent of histopathologic changes associated with this disease process, are not fully understood. CASE PRESENTATION: We present the case of an 8-year-1-month old patient with persistent anemia and who was initially diagnosed with Celiac disease before ultimately being diagnosed with alpha-mannosidosis...
