Exomic Sequencing Uncovers Novel Genetic Associations for Deciphering Developmental Disorders (DDD) Study Participants with Hypospadias, Cardiovascular and Neurodevelopmental Abnormalities

Gazdagh Gabriella , McGowan Ruth , Ahmed Faisal , DDD Study Faisal , Tobias Edward

Background: Hypospadias is a common characteristic of Disorders of Sex Development (DSD). At the present time a molecular diagnosis is not reached in over 50% of cases. The DDD Study represents a useful resource of large molecular and phenotypic datasets obtained from individuals with an undiagnosed developmental abnormality including DSD.Objective: To review associated features and identify likely pathogenic variants in previously undiagnosed DDD partic...

The Existence of an Androgen Responsive Transcriptome in the Peripheral Blood of Boys Extends the Utility of the HCG Stimulation Test

Rodie Martina , Herzyk Pawel , Mudaliar Manikhandan , Chudleigh Sandra , Tobias Edward , Ahmed Faisal

Background: The hCG stimulation test is a valuable method for assessing androgen production but there is a need to explore its utility in assessing androgen responsiveness and long-term prognosis.Objective and hypothesis: Our aim was to explore the effect of hCG stimulation on the peripheral transcriptome in boys undergoing investigation for DSD.Method: Thirteen boys undergoing investigation for 46,XY DSD received i.m. hCG 1500 U o...

Thioredoxin Reductase 2 (TXNRD2) Variant As A Cause Of Micropenis, Undescended Testis And Selective Glucocorticoid Deficiency

Patjamontri Supitcha , Lucas-Herald Angela , McMillan Martin , Prasad Rathi , Metherell Louise , McGowan Ruth , Tobias Edward , Faisal Ahmed S.

Introduction: The molecular aetiology of familial glucocorticoid deficiency (FGD) is very heterogeneous. A recent report of a genetic variant in TXNRD2, the gene encoding thioredoxin reductase Type 2, in a South Asian kindred with FGD suggests that the maintenance of redox balance may be critical for adrenocortical function. We present the second report of an individual from another south Asian family harbouring a different pathological variant in <em...

An Investigation Of Androgen-responsive Non-coding RNAs In Boys With Atypical Genitalia Without Genetic Variants in the Androgen Receptor (AR)

Alimussina Malika , McMillan Martin , Chudleigh Sandra , D McNeilly Jane , A Diver Louise , McGowan Ruth , S Tobias Edward , Faisal Ahmed S

Introduction: Recent studies point to the existence of androgen-responsive non-coding (nc) RNAs in peripheral blood mononuclear cells (PBMC) RNA.Aim: To quantify the androgen-responsive gene expression of SNORD5 and RNY5 and investigate their relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: 19 bo...

Phenotypic and Genetic Assessment of Boys with a Suspected XY Disorder of Sex Development

Alimussina Malika , Diver Louise A , McNeilly Jane D , Lucas-Herald Angela K , Tobias Edward S , McGowan Ruth , Faisal Ahmed Syed

Introduction: Among Disorders of Sex Development (DSDs), XY DSD, represents the most challenging group in terms of identifying a diagnosis.Objectives: The aim of the study was to determine the prevalence of biochemical and molecular genetic tests in a cohort of boys with XY DSD and to collate the phenotypes of patients with results of laboratory investigations and presence of associated abnormalities.Methods: New and existing cases...

Level of Uncertainty in Diagnostic Evaluation of Boys With XY Disorders of Sex Development (DSD)

Alimussina Malika , Diver Louise A , McNeilly Jane D , Lucas-Herald Angela K , Tobias Edward S , McMillan Martin , McGowan Ruth , Ahmed S Faisal

Introduction: The degree of consistency between the findings from next generation sequencing (NGS) and detailed endocrine assessment is unclear in boys with XY DSD.Objectives: Examine the range of endocrine and molecular genetic variation in boys undergoing evaluation for XYDSD.Methods: Boys with XYDSD who were evaluated in Glasgow from 2016 to 2018 were included. Sequence variants...
