Acromesomelic Dysplasia, Type Maroteaux (AMDM): Impact of Long-term (8 years) High-dose Growth Hormone Treatment on Growth Velocity and Final Height in Two Siblings

Arya Ved Bhushan , Raj Meena , Kapoor Ritika R , Chapman Simon A , Younes Maha , Irving Melita , Buchanan Charles R

Introduction: Acromesomelic dysplasia, type Maroteaux (AMDM) is a rare autosomal recessive skeletal dysplasia, characterized by severe dwarfism and disproportionate shortening of the extremities, predominantly affecting middle and distal limb segments. It results from loss-of-function mutations affecting the C-type natriuretic peptide (CNP) receptor (NPR-B), a transmembrane guanylyl cyclase receptor encoded by the NPR2 gene. Resistance to growth hormo...

EAP1 Mutations Cause an Impaired Transcriptional Activity on GnRH Promoter that Leads to Self-Limited Delayed Puberty

Mancini Alessandra , Howard Sasha R , Cabrera Claudia P , Barnes Michael R , Heger Sabine , Guasti Leonardo , Ojeda Sergio , Dunkel Leo

Background: The initiation of puberty is orchestrated by the augmentation in the secretion of gonadotropin-releasing hormone (GnRH) from a few thousand neurons located in the hypothalamus. Recent findings identified that the neuroendocrine control of puberty is regulated by a network of transcriptional factors hierarchically organized, but this still remains not fully elucidated. Enhanced At Puberty 1 (EAP1) is one of the main regulators of pubertal onset and it is ex...

LGR4 and EAP1 Mutations are Implicated in the Phenotype of Self-limited Delayed Puberty

Mancini Alessandra , Howard Sasha R , Ruiz-Babot Gerard , Cabrera Claudia P , Barnes Michael R , Guasti Leonardo , Dunkel Leo

Background: Aberrations in the timing of puberty may result in significant adverse health outcomes, including cancers, cardiovascular and neurological pathologies. Self-limited delayed puberty (DP) (i.e. constitutional delay of puberty) runs in families with either autosomal dominant or complex inheritance patterns in >70% of families, indicating a strong genetic basis of the trait. However, only a few genes have been identified underlying DP so far....

Oxytocin Improved Neurobehavioural Dysfunction in an Adolescent Post-Craniopharyngioma Surgery: A case report

Mann Amy , Fox Krystal , Kalitsi Jennifer , R Buchanan Charles , Bhushan Arya Ved , Paloyelis Yannis , R Kapoor Ritika

Background: Craniopharyngioma is a benign tumour that develops in the sellar and surrounding parasellar regions, including the hypothalamus and the pituitary gland responsible for the production and regulation of neuropeptides. Oxytocin is a hypothalamic neuropeptide that has been identified as a key modulator of appetite drive and social cognition. Here, we present a case of parent-observed improvements in neurobehavioural dysfunction following administration...

LGR4-Wnt β-Catenin Signalling Directs GnRH Network Development, with Defects Leading to Self-Limited Delayed Puberty

Mancini Alessandra , Howard Sasha R. , Cabrera Claudia P. , Barnes Michael R. , David Alessia , Wehkalampi Karoliina , Vassart Gilbert , Cariboni Anna , Garcia Marie Isabelle , Guasti Leonardo , Dunkel Leo

Background: The initiation of puberty is dependent upon an augmentation of gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. Development of the GnRH neuroendocrine network in embryonic life depends on coordinated migration of neurons from the vomeronasal organ in the nose to the forebrain. We have previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the ...

SOX3 Gene Duplication Associated with Midline CNS Malformations, Hypopituitarism and Neurodevelopmental Abnormalities: 5 Unrelated Cases

Chawla Garima , Nambisan Aparna K.R. , Arya Ved B. , Muhi-Iddin Nadia , Vamvakiti Katia , Ajzensztejn Michal , Hulse Tony , Buchanan Charles R. , Kapoor Ritika R.

Introduction: Duplications of SOX3 at Xq27.1 are known to be associated with a spectrum of midline defects, isolated/multiple pituitary hormone deficiencies and learning difficulties. We report 5 cases of SOX3 duplication with hypopituitarism and differing presentations. 1)Male neonate presented with poor feeding and prolonged jaundice. Investigations revealed central hypothyroidism and inadequate cortisol response to Synacthen. Appropriate hormone replacemen...

Introduction: Mutations of the PLS3 gene (MIM 300910), encoding plastin 3, are an extremely rare cause of osteogenesis imperfecta (OI). It has an X-linked inheritance and is characterized by early-onset osteoporosis and kyphosis, which can cause compression fractures, especially in the thoracic vertebrae. Although there are reports showing that bisphosphonates are effective in improving the bone mineral density of patients with PLS3 variants,...

Validation of Puberty Interpreter, a mobile application-based evaluation of pubertal disorders

Banerjee Sayan , Mehta Sajili , Sen Proteek , Narayanan R , Agrawal Manoj , Shukla Rishi , Bajpai Anurag

Background: Assessment of pubertal disorders is challenging for the pediatricians causing unnecessary evaluation on one hand while missing pathology on the other. The paucity of pediatric endocrine centers further adds to the problem in resource poor settings. We have developed puberty interpreter, a mobile application that provides instantaneous guidance regarding diagnosis and management of children and adolescents with concern for pubertal disorders based o...
