Objectives: To present the clinical profile, diagnostic work-up, and management of children with Disorders of Sexual Development (DSD).
Materials And Methods: A retrospective study from a tertiary pediatric endocrine unit of western India. We included 39 patients who presented over a period of 9 years from June 2009 to June 2018.
Results: Nineteen patients (48.7%) were diagnosed with 46 XY DSD, 16 (41%) with 46 XX DSD, and 4 (10.3%) with sex chromosomal DSD. Out of 46 XY DSD, androgen insensitivity was observed in 8 (42.1%) patients, 5 alpha-reductase deficiency in 5 (26.3%), gonadal dysgenesis in 3 (15.8%), ovotesticular DSD in 2 (10.5%) and 17 beta-hydroxylase (17γ-HSD3) deficiency in 1 (5.3%). Congenital adrenal hyperplasia was the most common cause in 46 XX DSD observed in 11 (68.75%) out of 16 patients, ovotesticular DSD was seen in 4 (25%) patients and testicular DSD in 1 (6.25%) patient. In sex chromosomal DSD 3 (75%) patients had mixed gonadal dysgenesis and 1 (25%) had ovotesticular DSD out of a total of 4 patients. At presentation gender of rearing was assigned as male in 16 (41%) patients, female in 20 (51.3%) patients, and no gender was assigned in 3 (7.7%). The gender of rearing was changed after diagnosis in 6 (16.7%) children.
Conclusion: CAH was the most common etiology of 46 XX DSD whereas androgen insensitivity among 46 XY DSD. Assigning the sex of rearing should not be hurried and should be done only after diagnosis and parental counseling. A multidisciplinary and systematic approach is required for children with DSD.

Background: 17α-Hydroxylase/17,20-lyase deficiency (17OHD) is a rare form of congenital adrenal hyperplasia (CAH), caused by mutations in the CYP17A1 gene. It typically manifests clinically as variable degree of hypertension, hypokalemia, and disorders of sexual development (DSD), which can include abnormal sexual differentiation in males and sexual infantilism in females. Over 100 mutations in CYP17A1 have been identified, with most cases involving missense mutations or small deletions.

Background: 46, XY disorders of sex development (DSD) are a group of highly heterogeneous conditions in which the molecular etiology remains unknown in a significant proportion of patients, even with massive parallel sequencing. Clinically significant copy number variants (CNVs) are identified in 20-30% of cases, particularly among those with gonadal dysgenesis (GD) and no molecular diagnosis.
Methods: Fourteen patients with 46, XY DSD due to GD in whom no pathogenic/likely pathogenic variants were found on next-generation sequencing using a targeted panel of 155 genes were screened for clinically significant CNVs using Affymetrix Comparative Genomic Hybridization (CGH).

46,XY differences/disorders of sex development (DSD) are genetically heterogeneous conditions characterized by atypical development of the reproductive system. MYRF, a gene encoding a transcription factor, has been identified as a potential causative gene for DSD and cardiac urogenital syndrome (CUGS). This study aims to delineate the clinical manifestations of patients with 46,XY DSD and MYRF mutations, encompassing both from our cohort and cases reported in the literature.

Aim: To give clinical, hormonal and molecular genetic characteristics of cases of 46,XY DSD associated with variants in the HSD17B3 gene.
Materials And Methods: The study included 310 patients with 46,XY DSD for the period from 2015 to 2019.
Introduction: Differentiated service delivery (DSD) models, which are mechanisms of HIV care that reduce provider visits and offer varied ART delivery methods, are scaling up across sub- Saharan Africa. It is unknown how the movement of patients to DSD models impacts services beyond ART, including the uptake and completion of tuberculosis preventive therapy (TPT).
Methods: Using the RE-AIM framework, we analyzed data from Opt4TPT, a longitudinal cohort study examining TPT delivery in South Africa and Zimbabwe.
