Sertoli cells control peritubular myoid cell fate and support adult Leydig cell development in the prepubertal testis

open access: yesDevelopment, 2014
Sertoli cells (SCs) regulate testicular fate in the differentiating gonad and are the main regulators of spermatogenesis in the adult testis; however, their role during the intervening period of testis development, in particular during adult Leydig cell (

MTSS2‐Related Disorder: Refining the Phenotype in Four New Cases and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MTSS2 encodes a protein highly expressed in the central nervous system, with a crucial role in neurodevelopment. The de novo recurrent variant c.2011C>T (p.Arg671Trp) was first identified in 2022 as cause of Intellectual Developmental Disorder with ocular anomalies and distinctive facial features (OMIM#620086).

Germline selection of PTPN11 (HGNC:9644) variants make a major contribution to both Noonan syndrome's high birth rate and the transmission of sporadic cancer variants resulting in fetal abnormality

open access: yesHuman Mutation, Volume 43, Issue 12, Page 2205-2221, December 2022., 2022
Mutation frequency heat map of spontaneous PTPN11 variants show spatial clustering in the testis due to germline selection explaining the high birth incidence of Noonan syndrome. Some somatic PTPN11 cancer mutations are similarly clustered in testis. Abstract Some spontaneous germline gain‐of‐function mutations promote spermatogonial stem cell clonal ...

Sertoli Cells Maintain Leydig Cell Number and Peritubular Myoid Cell Activity in the Adult Mouse Testis

open access: yesPLoS ONE, 2014
The Sertoli cells are critical regulators of testis differentiation and development. In the adult, however, their known function is restricted largely to maintenance of spermatogenesis.

Compound Heterozygous Variants in ZSWIM7 Gene Linked to Infertility and Its Role in Gonadal Development

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...

Lifelong testicular differentiation in Pleurodeles waltl (Amphibia, Caudata)

open access: yesReproductive Biology and Endocrinology, 2009
Background In numerous Caudata, the testis is known to differentiate new lobes at adulthood, leading to a multiple testis. The Iberian ribbed newt Pleurodeles waltl has been studied extensively as a model for sex determination and differentiation ...

Identification of Transdiagnostic Childhood Externalizing Pathology Within an Electronic Medical Records Database and Application to the Analysis of Rare Copy Number Variation

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Externalizing traits and behaviors are broadly defined by impairments in self‐regulation and impulse control that typically begin in childhood and adolescence. Externalizing behaviors, traits, and symptoms span a range of traditional psychiatric diagnostic categories.
