Clinical profile and management challenges of disorders of sex development in Africa: a systematic review

OBJECTIVES

To review the published literature regarding disorders of sex development (DSD) in Africa which will highlight clinical characteristics, and challenges of evaluation and treatment of DSD.

CONTENT

We performed systematic review of articles published on DSD in Africa between January 2001 and December 2020.

SUMMARY

Eighteen studies involving 1980 patients from nine countries were analyzed. Overall mean age at presentation was 9.3 years (range 1 day-33 years) with 52.5 and 45.1% reared as females and males, respectively, prior to presentation. Following evaluation however, 64% were assigned female sex, 32.1% were assigned male sex, and 21.8% of the cases required sex reassignment. Only 7 (38.9%) of the publications reported medical treatment of DSD, 4 (22.2%) reported on psychosocial management and 5 (27.8%) documented multidisciplinary team management. Barring regional variations, the documented challenges of management include delayed presentation, loss to follow up, financial challenges, and lack of facilities for care of DSD. Comparison of the cases managed in the last decade (2011-2020) with those managed in the earlier decade (2001-2010) showed a trend towards earlier presentation and reduced rate of sex reassignment in the last decade. However, the challenges persisted.

OUTLOOK

Barring regional differences, a high proportion of DSD in Africa may have delayed presentation with inappropriate sex of rearing, inadequate evaluation and need for sex reassignment. Specific efforts to improve time to diagnosis, patient evaluation, improvement of healthcare funding, and collaboration with more developed countries may improve the care of patients with DSD in Africa.

Analysis of the androgen receptor (AR) gene in a cohort of Indonesian undermasculinized 46, XY DSD patients

Background

Pathogenic variants in the androgen receptor (AR) gene located on chromosome Xq11-12, are known to cause varying degrees of undermasculinization in 46, XY individuals. The aim of this study was to investigate the frequency of pathogenic variants in the AR gene in a cohort of 46, XY undermasculinized individuals from Indonesia who were suspected of having androgen insensitivity syndrome (AIS). All patients with 46, XY DSD referred to our center between 1994 and 2019 were collected from our clinical database. All 46, XY DSD patients without a prior molecular diagnosis with an external masculinization score (EMS) ≤ 9 were included in this study. All exons and intron–exon boundaries of AR gene were analyzed using Sanger sequencing to identify pathogenic variants of the AR gene.

Results

A cohort of 75 undermasculinized patients were selected for the study. Direct Sanger sequencing of all eight exons of the AR gene led to a genetic diagnosis in 11 patients (14.67%). All of the variants identified (p.Arg841His; p.Ile604Asn; p.Val731Met; p.Pro672Ser; p.Gln739Arg; p.Ser302Glufs*3) have been previously reported in patients with AIS.

Conclusions

This is the first study in Indonesia that highlights the significance of molecular analysis in providing a definitive diagnosis of AIS for patients with 46, XY DSD undermasculinization. This is an uncommon finding in the Indonesian population presenting with 46, XY DSD undermasculinization. A genetic diagnosis allows optimal clinical management and genetic counseling for patients and their families. As 46, XY DSD can be caused by pathogenic variants in other genes involved in gonadal development and differentiation, further genetic analysis, such as whole exome sequencing, should be carried out on those patients that did not carry an AR variant.

Analytical Review of Contemporary Fatwas in Resolving Biomedical Issues Over Gender Ambiguity

Issues of gender ambiguity have been discussed over time from both Islamic and medical perspectives. In Islam, these issues are typically considered in the context of khunūthah (literally translated as hermaphroditism). While biomedical studies have appeared to provide a large amount of information on abnormal human biological development, i.e. Disorders of Sex Development (DSDs). However, the connection between these two fields has been given little attention. This research aims to determine the Islamic underpinnings through the fatwa around the globe. Thus, institutional fatwa organisations among Sunni schools of thought at the international, regional and national levels are observed. The fatwas regarding the management of individuals with gender ambiguity, not specifically on DSDs, are chosen and presented accordingly. Based on the findings, the sporadic fatwas from different parts of the world delineate the issue of sex ambiguity and seem to be able to provide general guidelines for management of Muslim patients with DSDs. Three common aspects have been discussed including the methodology of gender assignment, the decision-making process and the surgical and hormonal treatments.
