Recent advances in cardiovascular genetics have transformed genetic testing into a valuable part of management of families with inherited cardiomyopathies. As novel mutations have been identified, understanding when to consider genetic testing has emerged as an important consideration in the management of these cases. Specific genetic testing has a paramount importance in the risk stratification of family members, in the prognosis of probands at higher risk of a serious phenotype expression, and finally in the identification of new mutations, all of which are discussed in this review. The indications for each type of cardiomyopathy are described, along with the limitations of genetic testing. Finally, the importance of public sharing of variants in large data sets is emphasized. The ultimate aim of this review is to present key messages about the genetic testing process in order to minimize potential harms and provide suggestions to specialized clinicians who act as a part of a multidisciplinary team in order to offer the best care to families with inherited cardiomyopathies.

An augmented transformer model trained on protein family specific variant data leads to improved prediction of variants of uncertain significance.

Variants of uncertain significance (VUS) represent variants that lack sufficient evidence to be confidently associated with a disease, thus posing a challenge in the interpretation of genetic testing results. Here we report an improved method for predicting the VUS of Arylsulfatase A (ARSA) gene as part of the Critical Assessment of Genome Interpretation challenge (CAGI6). Our method uses a transfer learning approach that leverages a pre-trained protein language model to predict the impact of mutations on the activity of the ARSA enzyme, whose deficiency is known to cause a rare genetic disorder, metachromatic leukodystrophy.

Objective: Ciliary body medulloepithelioma (CBME), a pediatric intraocular tumor with potential for locally aggressive behavior and metastasis, may present with a diverse spectrum of clinical and histopathologic features leading to diagnostic and management challenges. Examination of unusual CBME cases highlights challenges and modern diagnostic techniques which facilitate accurate diagnosis and guide management.
Methods: A retrospective clinicopathologic analysis of 6 patients with unusual clinical or pathologic features of CBME was performed.
Pharmacogenetic Testing for Predicting Methylphenidate Treatment Outcomes in Childhood Attention Deficit Hyperactivity Disorder in Turkey: Focus on Carboxylesterase 1, Latrophilin-3, and Catechol-O-Methyltransferase.

Pharmacogenetic studies involving Carboxylesterase 1 (CES1), Latrophilin-3 (LPHN3), and Catechol-O-methyltransferase (COMT) revealed individual differences regarding therapeutic response in children with attention deficit hyperactivity disorder (ADHD) under methylphenidate (MPH) treatment. This study aimed to evaluate MPH's association with the adverse effect status in children and its relationship with CES1, LPHN3, and COMT in the Turkish population. The study included 102 children and adolescents with ADHD, who were categorized as responders, or the adverse effect group based on their treatment response.

Summary: Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees.

Summary: Short stature is a common complaint among pediatric visits and the differential diagnosis is extensive. Although some variations in growth are normal, deviation from normal growth is often the first symptom of chronic disease in children. This is true for hormone abnormalities including growth hormone deficiency, hypothyroidism and glucocorticoid excess.
