Gene dosage of DAX-1, determining in sexual differentiation: duplication of DAX-1 in two sisters with gonadal dysgenesis

open access: yesMolecular Biology Reports, 2019
Two sisters phenotypically normal females, presenting with tumor abdominal mass with histopathological findings of teratoma and gonadoblastoma associated to 46,XY male-to-female sex reversal syndrome, secondary to a duplication in DAX-1, possibly ...

Genomic analysis of P elements in natural populations of Drosophila melanogaster [PDF]

open access: yesPeerJ, 2017
The Drosophila melanogaster P transposable element provides one of the best cases of horizontal transfer of a mobile DNA sequence in eukaryotes. Invasion of natural populations by the P element has led to a syndrome of phenotypes known as P-M hybrid ...

Whole exome sequencing combined with linkage analysis identifies a novel 3 bp deletion in NR5A1 [PDF]

open access: yes, 2015
Disorders of sex development (DSDs) encompass a broad spectrum of conditions affecting the development of the gonads and genitalia. The underlying causes for DSDs include gain or loss of function variants in genes responsible for gonad development or ...

Management issues in mixed gonadal dysgenesis (45,X/46,XY mosaicism)

open access: yesJournal of Medical and Scientific Research, 2015
Mixed gonadal dysgenesis (45X/46XY and its variants) is a form of sex chromosome DSD (disorders of sex development). The clinical presentation of such patients is highly variable and mild variants may go unnoticed.

Spreading the clinical window for diagnosing fetal-onset hypogonadism in boys [PDF]

open access: yes, 2014
In early fetal development, the testis secretes – independent of pituitary gonadotropins – androgens and anti-Müllerian hormone (AMH) that are essential for male sex differentiation. In the second half of fetal life, the hypothalamic–pituitary axis gains

Classical gonadoblastoma: its relationship to the “dissecting” variant and undifferentiated gonadal tissue [PDF]

open access: yes, 2017
Classical gonadoblastoma occurs almost entirely in the dysgenetic gonads of an individual who has a disorder of sex development. Approximately 40% of such neoplasms are bilateral.

Case report of whole genome sequencing in the XY female: identification of a novel SRY mutation and revision of a misdiagnosis of androgen insensitivity syndrome [PDF]

open access: yes, 2016
Background: The 46,XY female is characterised by a male karyotype and female phenotype arising due to any interruption in the sexual development pathways in utero. The cause is usually genetic and various genes are implicated.
