Gender Identity Prediction in Adulthood by HTP Test (House-Tree-Family) in 46, XY DSD Patients

Batista Rafael Loch , Inacio Marlene , Oliveira Jr Ari , Brito Vinicius N , Costa Elaine M F , Domenice Sorahia , Mendonca Berenice B

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Background: Outcomes related to sexual life are poorly explored in 46,XY DSD patients and most studies focus only in 46,XX DSD (CAH). In 46,XY DSD the observations of sexual outcomes are scares, but they overall indicate that the SexQoL is impaired, particularly regarding sexual function and sexual satisfaction.Objective and hypotheses: To evaluate sexual outcomes in a cohort of patients with 46,XY in adulthood and compare these observations with the res...

Characterisation of Mutations in the Androgen Receptor Identified in 38 Brazilian Families with Complete or Partial Androgen Insensitivity Syndrome

Batista Rafael Loch , Santi Andreza , Arnhold Ivo J P , Cunha Flavia S , Costa Elaine M F , Mendonca Berenince B , Domenice Sorahia

Background: Androgen insensitivity syndrome (AIS) is a genetic disease X-linked, caused by functional abnormalities of the androgen receptor (AR). Mutations in the AR are associated with broad phenotypic spectrum from partial insensibility (PAIS) to complete insensitivity (CAIS).Objective and hypotheses: To characterize the mutations (MUT) identified in the AR in 38 Brazilian families with AIS. The MUT were analyzed considering their type, location in th...

Gonadal tumor risk, bone mineral density, and genetics, clinical, hormonal, and psychosexual aspects of a large androgen insensitivity syndrome cohort

Introduction: Androgen Insensitivity Syndrome (AIS) is the most common cause of Differences of Sexual Development (DSD) in 46, XY individuals. It is an X-linked genetic disease caused by allelic variants in the Androgen Receptor Gene (Xq11-12). Methods: Patients with clinical suspicion of AIS performed hormonal serum measurements (LH, FSH, estradiol, testosterone) and molecular sequencing of the AR gene, including exons and the 5’UTR region. Psychosexual variab...

Introduction: The Wilms tumor suppressor gene 1 (WT1) plays an essential role in urogenital and kidney development. Heterozygous germline mutations in WT1 have been classically associated with Denys–Drash (DDS) and Frasier syndrome (FS). Exonic missense mutations in the zinc-finger region are the cause of DDS and mutations affecting the canonic donor KTS splice site of intron 9 are the cause of FS. New phenotypes, as 46,XX testicular DSD...

Background: Most published studies on 46,XY DSD focused on genetic findings without association with biochemical work-up.Objectives: To retrospectively analyze the clinical and genetic findings of a large cohort of 46,XY DSD patients.Methods: 285 non-syndromic 46,XY DSD individuals (192 sporadic and 89 familial cases) were studied. LH, FSH, testosterone (T), androstenedione (A) wer...

DEAH-Box Helicase 37defects (DXH37) Deffects are a Novel Cause of 46,XY Gonadal Dysgenesis

Background: 46,XY gonadal dysgenesis (GD) is a spectrum disorder which lead to variable degrees of atypical external genitalia, ranging from female to micropenis and absent of gonadal tissue (known as Embryonic Testicular Regression Syndrome -ETRS). Most patients with 46,XY GD remains without a molecular diagnosis.Objective: To report the DEAH-box helicase 37 gene (DHX37) as a novel candidate for the GD etiology.Patients a...
