Fertility of Women Treated During Childhood for Precocious Puberty with Triptorelin: PREFER Retrospective Study

Carel Jean-Claude , de Mouzon Jacques , Blumberg Joelle

Introduction: There are few published large-cohort studies examining the long-term impact of GNRH analogue treatment for precocious puberty (PP) on fertility in women. The PREFER study analysed fertility in a large cohort of women treated during childhood for PP with triptorelin.Methods: PREFER was a longitudinal, descriptive, non-comparative, epidemiological study conducted in 23 centres in France between February 2007 and November 2009. Women aged &#88...

Loss-Of-Function and Missense Mutations in MYRF are a Novel Cause of Autosomal Dominant 46,XY Leydig Cell Hypoplasia and 46,XY Gonadal Dysgenesis

McElreavey Ken , Globa Evgenia , Bertalan Rita , Bignon-Topalovic Joelle , Brauner Raja , Bashamboo Anu

MYRF is known to regulate the myelination of the central nervous system and mice with a conditional deletion of MYRF in oligodendrocyte precursors has anomalies of motor skill. Recently, several loss-of-function and missense mutations in MYRF have been reported in association with syndromic forms of congenital heart disease (CHD) with elements of Scimitar syndrome and/or with congenital diaphragmatic hernia (CDH). In most 46,XY individuals a range of...

Mutations Involving Nuclear Receptors and Their Cofactors as a Major Cause of 46,XX DSD

The genomic analysis of 46,XX individuals with testes (known as testicular Disorders/Differences of Sex Development (TDSD) or ovotestes (ovotesticular DSD (OTDSD)) supports the hypothesis that ‘pro-testis/anti-ovary’ or ‘pro-ovary/anti-testis’ genetic pathways exist. These children typically present with virilized genitalia due to testosterone production from the presence of testicular tissue. Many individuals with TDSD and a minority with OTDSD have a tran...

A Mutation in WT1 (Wilms’ Tumor Suppressor 1) Associated with 46,XX TDSD

Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...

MAP3K1 Mutation in a Patient with Complete XY Gonadal Dysgenesis

Kohler Birgit , Gehrmann Nicole , Gruters-Kieslich Annette , Bignon-Topalovic Joelle , McElreavey Kenneth , Bashamboo Anu

Background: 49,XY gonadal dysgenesis (GD) is a very rare disorder of testes development with an incidence of 1:50–100 000. MAP3K1 is a MAPK that mainly regulates the MAPK pathways. High Map3k1 expression was found in female and male mice gonads at 13.5 dpc. In 2010, MAP3K1 mutations were identified in two families with complete and partial XY GD and in two unrelated sporadic cases with complete XY GD (Pearlman 2010 AJMG). Recently, four additional mutations (four out of 4...

Background: For young adults with type 1 diabetes, transition from a paediatric setting to an adult care setting is a vulnerable period with risks for gaps in care. These emerging adults need to develop skills for managing their diabetes yet it is often challenging to cover all anticipatory guidance topics related to type 1 diabetes. In the context of a structured transition clinic, we hypothesized that by leveraging teens’ facility with technology and marketing/design we...

Mutations in the DEAH-box RNA Helicase DHX37 are a Frequent Cause of 46,XY Gonadal Dysgenesis and 46,XY Testicular Regression Syndrome

XY individuals with Disorders/Differences of Sex development (DSD) are characterized by reduced androgenization caused, in some children, by gonadal dysgenesis or, more rarely, testis regression during early fetal development. The genetic etiology for most patients with 46,XY gonadal dysgenesis and for all patients with testicular regression syndrome (TRS) is unknown. Identification of novel genes involved in DSD is crucial for providing an accurate clinical diagnosis, aiding ...

Silver Russell syndrome: A Cause of Partial IGF1 Resistance?

Dufourg Marie-Noelle , Perin Laurence , Houang Muriel , Daubard Marie-Laure , Brioude Frederic , Bouc Yves Le , Netchine Irene

Background: Silver-Russell syndrome (SRS) is characterized by intrauterine and postnatal growth retardation, relative macrocephaly at birth, prominent forehead, severe feeding difficulties and body asymmetry. In around 50%, it is secondary to hypomethylation at the IGF2/H19 imprinted locus on 11p15 (11p15 LOM), and in 10% to a maternal disomy of chromosome 7 (mUPD7). Mechanisms of postnatal growth failure in SRS are not well understood.Objective and hypo...
