Mol Genet Genomic Med. 2018 Sep;6(5):785–795.doi: 10.1002/mgg3.445. PubMed PMID: 29998616Chromobox protein homolog 2 (CBX2) has two isoforms, CBX2.1 and the shorter CBX2.2. CBX2.1 was previously shown to be essential for male gonadal development, when a mutation was identified in a girl with 46,XY DSD. CBX2.1 stimulates male-specific...

Brief summary: This cross-sectional single tertiary center study analyzed the aspects of sexual life and fertility desire among a large cohort of adults with 46,XY DSD in Brazil. The influence of critical variables such as external genital appearances, prenatal androgen exposure, and gender change in the sexuality of 46,XY DSD people were investigated.There is sparse literature on the sexual function of 46,XY DSD conditions due to their rarity and hetero...

Brief summary: This translational study showed an increased plasma expression of miR-210 in individuals with 46,XY DSD compared to the control population and also showed a positive association between the presence of atypical genitalia and plasma levels of miR-210 expression in individuals with 46,XY DSD. The findings of this study contribute to a novel perspective on the possible role of miRNAs in the development of the male external genitalia and in the development of phenot...

PMID: 33156432.Brief Summary: Pituitary gigantism is a rare disease, which can be syndromic, as in McCune-Albright syndrome, Carney complex, MEN1 and MEN4, and the newly described “three P association” (paraganglioma, pheochromocytoma and pituitary adenoma) (1), or non-syndromic caused by mutations ...

Brief Summary: This retrospective clinical research reports the clinical/biochemical, radiological, and genetic findings of a large cohort of 209 non-syndromic 46,XY DSD patients from a single tertiary center collected over the last 25 years in Brazil. A molecular diagnosis was achieved in 59....

PMID: 31613957.Mineralocorticoid (MC) replacement therapy along with glucocorticoid (GC) replacement is crucial to avoid life-threating adrenal crises in Addison´s disease (AD) and in classical CAH (1–3). MC is administered with the aim of achieving plasma renin concentration (PRC) within the upper limit of ...

Brief Summary: This international cohort study of 404 patients identified rare likely damaging variants in the gene MECP2 in patients with central precocious puberty. Translational experiments showed that GnRH neurons in mice express Mecp2.Over the last few years, several studies have provided insight into the epigenetic regulation of the onset of puberty1-3. DNA methylation, histone post-translational modifications and non-c...

Am J Hum Genet. 2021 Aug 5;108(8):1526-1539. doi: 10.1016/j.ajhg.2021.06.013. PMID: 34270938.Brief Summary: This study reports splice-disruptive variants in POU1F1 in 4 families with hypopituitarism and uses a high-throughput splicing reporter assay to create a comprehensive catalogue of such variants in or near exon 2 of the gene. The catalogue paves the way for identifying synon...
