Brief summary: Two unrelated patients with a disorder of sex development (DSD) phenotype of partial androgen insensitivity (PAIS) showed heterozygous variants in the DAAM2 gene. Their genital skin fibroblasts showed reduced dihydrotestosterone-stimulated androgen receptor (AR) activity. Extensive basic studies revealed the underlying mechanism of the DSD in which DAAM2-regulated actin polymerization at the ligand-inducible androgen receptor is required for androgen-st...

Nat Med. 2020 Oct;26(10):1583–1592 Abstract: https://pubmed.ncbi.nlm.nih.gov/32807933/In brief: Improved treatments for osteoarthritis and other degenerative joint diseases are urgently needed. This study demonstrates, for the first time, that the synovial microenvironment can be modified to allow resident skeletal stem cells to form hyaline articular cartilage and thereby reg...

Proc Natl Acad Sci USA. 2020 Jun 16;117(24):13680–13688. 10.1073/pnas.1921676117. PMID: 32493750.On the search for a genetic cause for 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants were found in the 4th zinc finger (ZF4) of the Wilms tumor 1 gene (<em...

J Clin Endocrinol Metab. 2021 Mar 25;106(4):1111–1128.https://pubmed.ncbi.nlm.nih.gov/33382876/In this multicentre patient cohort study, the authors investigated the use of targeted metabolomics to discriminate primary hypertension (PHT) from endocrine forms of hypertension (EHT). They identified 16 metabolites that help to discriminate between PHT and EHT.Arteri...

Genet Med. 2021 Dec;23(12):2443-2447.Abstract: https://pubmed-ncbi-nlm-nih-gov.proxy.kib.ki.se/34341520/In brief: In achondroplasia, longitudinal bone growth is inhibited resulting in severe, disproportionate short stature. In this open-label extension study of participants from the phase 3 study, daily subcutaneous injection of vosoritide during 104 weeks resulted in increa...

Cell metabolism 2022;34(2):329-45.e8. doi: 10.1016/j.cmet.2021.12.016Brief Summary: In a mouse model, time of exercise during the day was found to determine the magnitude and type of metabolic response. Different tissues responded to exercise at different times of the day.Comment: Exercise is considered a vital intervention in the prevention and treatment of individu...

N Engl J Med. 2021;385(17):1581-92. doi: 10.1056/NEJMoa2103329.PubMed ID: 34614324Brief Summary: The authors performed whole exome sequencing in 2548 children with severe obesity and identified 22 GNAS mutation carriers, almost all of which disrupted melanocortin 4 receptor (MC4R) signaling.The gene GNAS encodes the stimulatory G-protein alpha subunit pr...

Nat Med. 2022;28(4):814-22. doi: 10.1038/s41591-022-01714-5.PubMed ID: 35314841Brief summary: This study performed large-scale metabolomic profiling across 14 000 adults from 4 cohorts and identified 17 steroid metabolites whose levels were reduced in individuals with prevalent asthma. The largest reductions were associated with inhaled corticosteroid (ICS) treatment, and these were valida...

To read the full abstract: J Clin Endocrinol Metab, March 2020, 105(3):e70–e84A cohort of 21 adult males (aged 19 to 89 years) harboring hemizygous pathogenic IGSF1 gene mutations underwent anthropometry, endocrine testing, testis ultrasonography, and body composition assessment to define the pathophysiological role of IGSF1 in influencing GH secretion. In addition, two lines of Igsf1 -deficient male mice were use...
