Purpose Of Review: Our knowledge of the genetic basis and molecular pathogenesis of hypertrophic cardiomyopathy (HCM) continues to evolve. We describe the genetic basis of HCM, recent advances in genetic testing and the role of genetics in guiding risk stratification and management, both now and in the future.
Recent Findings: While initially thought to be an exclusively Mendelian disease, we now know there are important HCM sub-groups. A proportion will have sarcomere variants as the cause of their disease, while others will have genetic variants in genes that can give rise to conditions that can mimic HCM. The role of genetics is primarily for cascade genetic testing, though there is emerging evidence of a role for prognosis and patient management. Genetic testing is a useful addition to management. Genotype may play a greater role in risk stratification, management, treatment and prognosis in future, offering improved outcomes for patients and their families with HCM.

Purpose: To explore the genetic cause of children with unidentified etiology of neurodevelopmental disorders, thus providing references for the diagnosis, treatment and genetic counseling.
Design And Methods: Children with neurodevelopmental disorders but unidentified etiology in the Child Healthcare Department, Children's Hospital of Nanjing Medical University from November 2018 to December 2021 were retrospectively analyzed. A total of 2 ml of peripheral venous blood was collected from the child and their parents for the whole exome sequencing (WES) and copy number variation (CNV) detection.

Congenital hypogonadotropic hypogonadism (CHH) can cause delayed secondary sexual characteristics and contribute to juvenile osteoporosis, with multiple causative genes having been reported. We treated a 27-year-old man diagnosed with central hypogonadism, presenting with delayed secondary sexual characteristics and juvenile osteoporosis, using bone resorption inhibitors and testosterone therapy. Genetic testing revealed missense variants both in the fibroblast growth factor receptor 1 () and gonadotropin-releasing hormone receptor () genes, a combination that has not been previously reported.

Background: Very long-chain acyl-coenzyme A dehydrogenase deficiency (VLCADD) is a rare autosomal recessive disease associated with variants in the gene.
Methods: In December 2021, a neonate with VLCADD was identified via newborn screening in Xuzhou, China. Genetic testing and genetic family verification were performed via high-throughput sequencing combined with Sanger sequencing.

Objective: Carotid body tumors (CBTs) are rare neoplasms of the paraganglia at the carotid bifurcation. While typically benign, CBTs occasionally exhibit malignancy, metastasizing to nearby lymph nodes. Histopathologic analysis alone is insufficient to confirm malignancy, requiring metastases to non-neuroendocrine tissue for a definitive diagnosis.
