Objective: Spondyloepiphyseal dysplasia tarda (SEDT) is a rare hereditary bone disease characterized by spinal and epiphyseal anomalies. We identified the disease by gene sequencing in a Chinese pedigree with SEDT.

Methods: We extracted genomic DNA from five members of a four-generation Chinese SEDT kindred with three affected males and then analyzed the genetic mutation by PCR and DNA sequencing.

Results: DNA sequencing showed that the genetic missense mutation occurred one bp upstream of exon 6 in the gene in two families, and a heterozygous mutation was found in a female carrier. In addition, no mutation was found in the other members of the family.

Conclusion: SEDT in this family was caused by a G/C missense mutation in exon 6 of the gene, previously not shown to be associated with X-linked SEDT.

Aims: Sarcoendoplasmic reticulum Ca-ATPase 2 (SERCA2), encoded by ATP2A2, is a key protein involved in intracellular Ca homeostasis. The SERCA2a isoform is predominantly expressed in cardiomyocytes and type I myofibres. Variants in this gene are related to Darier disease, an autosomal dominant dermatologic disorder, but have never been linked to myopathy.

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.

A rare haplotype of the GJD3 gene segregating in familial Meniere's disease interferes with connexin assembly.

Genome Med

January 2025

Otology & Neurotology Group CTS495, Instituto de Investigación Biosanitario, Ibs.GRANADA, Universidad de Granada, 18071, Granada, Spain.

Background: Familial Meniere's disease (FMD) is a rare polygenic disorder of the inner ear. Mutations in the connexin gene family, which encodes gap junction proteins, can also cause hearing loss, but their role in FMD is largely unknown.

Methods: We retrieved exome sequencing data from 94 individuals in 70 Meniere's disease (MD) families.

Genetic and clinical spectrum of steroid-resistant nephrotic syndrome with nuclear pore gene mutation.

Pediatr Nephrol

January 2025

Department of Nephrology, Wuhan Children's Hospital (Wuhan Maternal and Child Healthcare Center), Tongji Medical College, Huazhong University of Science & Technology, Wuhan, China.

Background: Steroid-resistant nephrotic syndrome (SRNS) is insensitive to steroid therapy and overwhelmingly progresses to kidney failure (KF), the known pathogenic genes of which include key subunits of the nuclear pore complex (NPC), a less-recognized contributor to glomerular podocyte injury.

Methods: After analyzing their clinical characterizations and obtaining parental consent, whole-exome sequencing (WES) was performed on patients with SRNS. Several nucleoporin (NUP) biallelic pathogenic variants were identified and further analyzed by cDNA-PCR sequencing from white cells of peripheral blood, minigene assay, immunohistochemical (IHC) staining, and electron microscopy (EM) ultrastructure observation of kidney biopsy, as well as multiple in silico prediction tools, including 3D protein modeling.

Background: -related disorders are autosomal recessive genetic disorders characterized by movement disorders primarily including ataxia and spasticity, mainly accompanying developmental delay, seizures, and neuroimaging abnormalities. -related spectrum disorder (VSD) may better reflect the characteristics of the disease. So far, the relationship of genotype and phenotype of VSD has not been established.
