Clin Endocrinol Metab. 2021;106(2):431–441. doi: 10.1210/clinem/dgaa842. PMID: 33205215This study aimed to describe the clinical characteristics of 6 patients with NPR2 gene mutations and the response to rhGH treatment in 2 of them.The natriuretic peptide receptor 2 gene (NPR2) is a paracrine factor involved in the regulation of cell proliferati...

J Pediatr Endocrinol Metab 2019; 32(3): 253–258. DOI: 10.1515/jpem-2018-0342• 44,360 neonates were screened for CAH as part of a pilot screening programme in Beijing.• In this prospective study, a CAH incidence of 1:7393 was found, and the most common 21 OHase mutation was c.293-13C/A>G.The authors describe the results of a ...

Overall, 13.15% (n =847,737) had impaired fasting glucose and 1.18% (n =76,297 women) had diabetes, of whom only...

However, current treatment guidelines for CAH regard this treatment still as experimental, mainly because follow-up studies of treated fetu...

Brief Summary: This prospective cohort study of 146 mother-neonate pairs determined fetal-maternal exposure to EDCs from October 2021 – October 2022 and examined their associations with fetal growth parameters. Fetal exposure to bisphenol-A (BPA) showed a linear association with asymmetric fetal growth patterns.Their definition of fetal growth restriction (FGR) when assessed by transabdominal ultrasonography at 38.3 weeks gestational age was a fetal...

Brief summary: In this in vivo study, Xia et al. demonstrate that AAV-mediated gene therapy recovers testosterone levels, restarts sexual development, restores spermatogenesis, and produces fertile offspring in a mouse model of Leydig cell failure (LCF).A null mutation in the gene encoding luteinizing hormone/choriogonadotrophin receptor (Lhcgr) causes a hereditary LCF in mice which is characterized by a reduction in testosterone levels...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...

Nat Genet. 2021 Jul;53(7):962-971. https://pubmed.ncbi.nlm.nih.gov/34127860/Brief Summary: The authors report the largest and most diverse genome-wide association study (GWAS) of type 1 diabetes (T1D) to date, including 61,427 participants from different ancestries. It identified 78 significant genomic regions associated with T1D, of which 36 were new. The integration of genetic evidence, f...

Recent studies suggest that the genetic basis of self-limited delayed puberty is likely to be highly heteroge...
