Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal curvature deformity that appears in the adolescent period. In this study, we performed whole-exome sequencing on 11 unrelated Taiwanese patients with a Cobb's angle greater than 40 degrees. Our results identified more than 200 potential pathogenic rare variants, however, most of which were carried only by one individual. By in silico pathogenicity annotation studies, we found that , , and were the most important genes, as multiple pathogenic variants were within these genes. Furthermore, biological functional annotation indicated critical roles of these AIS candidate genes in the skeletal muscle. Importantly, a pathogenic variant on was shared by over 35% of the patients. These results highlighted , , and as the most likely susceptibility genes for severe AIS.

Background: Male EBP disorder with neurologic defects (MEND syndrome) is an extremely rare disorder with a prevalence of less than 1/1,000,000 individuals worldwide. It is inherited as an X-linked recessive disorder caused by impaired sterol biosynthesis due to nonmosaic hypomorphic EBP variants. MEND syndrome is characterized by variable clinical manifestations including intellectual disability, short stature, scoliosis, digital abnormalities, cataracts, and dermatologic abnormalities.

Hearing loss is one of the conditions characterized by a high degree of genetic heterogeneity, and whole exome sequencing (WES) serves as a key method for identifying pathogenic variants. To date, 155 genes have been reported to be associated with nonsyndromic hearing loss. Recently, a study by Velde et al.

Background: This study aims to identify a pathogenic SDHD mutation associated with hereditary head and neck paraganglioma (HNPGL) in a Chinese family and to explore its implications for genetic counseling.
Methods: The study involved a family with 15 members spanning three generations. A 31-year-old patient (II-4) was diagnosed with a left parotid gland tumor and a right carotid body tumor, while both the father and elder sister had right carotid body tumors, and the third sister had bilateral carotid body tumors.

Background: Mucopolysaccharidosis type I (MPS I - IDUA gene) is a rare autosomal recessive lysosomal storage disorder. Clinical symptoms, including visceral overload, are progressive and typically begin postnatally. Descriptions of hepatosplenomegaly associated with lysosomal pathology are uncommon during the prenatal period.

Purpose: This study identified novel variants of the FSIP2 and SPEF2 genes in multiple morphological abnormalities of the sperm flagella (MMAF) patients and to investigate the potential effect of variations on male infertility and assisted reproductive outcomes.
Methods: Whole-exome sequencing was performed in 106 Chinese MMAF patients. The discovered variants were evaluated in silico and confirmed by Sanger sequencing.
