Six novel variants in the MKRN3 gene causing central precocious puberty: characteristics of ten patients and their affected relatives

Gernay Caroline , Brachet Cecile , Tenoutasse Sylvie , Boros Emese , Libioulle Cecile , Heinrichs Claudine ,

Background: In 2013, Abreu et al identified loss-of function mutation in the MKRN3 gene of fifteen patients from five families with idiopathic central precocious puberty (iCPP), highlighting the implication of this maternally imprinted gene in this still poorly understood condition. Since this study, other mutations have been described and now represent the most common genetic cause of iCPP.Objective: The objective of th...

Neonatal TSH screening for congenital hypothyroidism: before discharge or at home?

In Belgium, neonatal TSH screening for congenital hypothyroidism has been performed between day 3 and 5 of life since the late seventies. In January 2015, a policy of early discharge of healthy neonates was implemented so that the neonatal screening strategy had to be adapted. Between January 2015 and September 2019, dried blood spot sampling was mostly collected at home AFTER discharge at 72 h of life (Newborn Screening Strategy 1 (NBS1)). After October 2019, sampling was mos...

Background: A combination of GH and a gonadotropin releasing hormone analogue (GnRH a) is hypothesized to improve adult height in children with a poor adult height prediction.Study design: In this multicenter study, 24 girls in early puberty (bone age ≤12.0 y),with a predicted adult height ≤151.0 cm and normal body proportions were treated with GH (Zomacton) 50 μg/kg per day and triptorelin (Gonapeptyl) 3.75 mg/month SC or IM (for 4 year...

The ZOMATRIP Study: 4 Year Combination Therapy of GH and GnRHa in Girls with a Short Predicted Adult Height During Early Puberty: Interim Results at the End of the Treatment Phase

Background: A combination of GH and a GnRH agonist is sometimes used to improve adult height in children with a poor height prediction, only few studies support this.Study design: In this multicenter study, 24 short girls in early puberty, with a bone age below 12.0 years, an adult height prediction below 151.0 cm and normal body proportions were treated with GH (Zomacton) transjections 50 μg/kg per day and triptorelin (Decapeptyl) i.m. (3.75 mg/mon...

Background: Hereditary Hypophosphatemic Rickets (HHR) is caused by persistently elevated FGF23 resulting in renal phosphate wasting and decreased 25 vitamin D hydroxylation. Treatment with vitamin D analogues (VDA) has been added to phosphate supplements in the late seventies.Objective and hypotheses: Our objective was to evaluate the outcomes of VDA and phosphate supplements in adult patients with HHR in comparison with patients who did not receive VDA ...

Background: Bilateral testicular regression (BTR) is characterized by the absence of both testicles in a newborn male or shortly thereafter, and presenting as bilateral cryptorchidism with undetectable AMH levels and the absence of Müllerian structures on pelvic ultrasound. Depending on when the regression occurs during fetal development, the condition can be associated with a micropenis. Few studies have explored the etiology and long-term outcome of BTR...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...
