FESTA ADALGISA , GRANDONE ANNA , LUONGO CATERINA , CIRILLO GRAZIA , del GIUDICE EMANUELE MIRAGLIA

A 5-year old boy was referred to our clinic for short stature reported since first years of life. At birth weight and length were normal, psychomotor development was regular, target height was 165.9 cm. At 7 months of life he was subjected to correction of cleft lip-palate. Since 3 years of life he suffered from headache, for which a fundoscopy was performed and revealed a Morning Glory Disc Anomaly (MGDA) of the right eye. At our first visit height was 98.2 cm (-2.5DS), body ...

Basal Levels of 17-hydroxyprogesterone can Distinguish Isolated Precocious Pubarche from Non-Classical Congenital Adrenal Hyperplasia in Children: A Prospective Observational study

Grandone Anna , Festa Adalgisa , Mariani Michela , Luongo Caterina , Giudice Emanuele Miraglia del

Background: Basal levels of androgens, in particular 17-OHprogesterone (17OHP), are widely debated as predictors of non-classical congenital adrenal hyperplasia (NCCAH) among patients with precocious pubarche (PP). So many authors suggested the execution of ACTH stimulation test in all children with PP. The aim of our study was to identify clinical and biochemical predictors of NCCAH in children with PP.Methods: We conducted a prospective study of 92 pat...

MKRN3 Levels in Girls with Central Precocious Puberty During GnRHa Treatment: A Longitudinal Study

Grandone Anna , Cirillo Grazia , Sasso Marcella , Luongo Caterina , Tornese Gianluca , Festa Adalgisa , Giudice Emanuele Miraglia Del

Background: Recently, mutations of makorin RING-finger protein 3 (MKRN3) have been identified in familial central precocious puberty (CPP). Serum levels of this protein decline before the pubertal onset in healthy girls and boys and are lower in patients with CPP compared to prepubertal matched pairs. The aim of the study is to investigate longitudinal changes in MKRN3 circulating levels in patients with CPP before and during GnRHa treatment.Me...

Molecular Screening of MKRN3, DLK1 and KCNK9 Genes in Central Precocious Puberty

Grandone Anna , Sasso Marcella , Cirillo Grazia , Luongo Caterina , Mariani Michela , del Giudice Emanuele MIraglia , Perrone Laura

Background: Central precocious puberty (CPP) is often familial but its genetic cause is largely unknown. Very recently, the makorin RING finger protein 3 (MKRN3) gene has been found mutated for the first time in 5 families with familial precocious puberty. The inheritance pattern is particular being the MKRN3 a maternal imprinted gene. Moreover in a recent genome wide association study common intronic or intragenic variants harbouring this gene and other two imprinted genes, D...

A New Case of Intragenic Deletion in IGF1R with Very Mild Phenotype

Coppola Ruggero , Luongo Caterina , Nacca Raffaella , Sasso Marcella , Grandone Anna , del Giudice Emanuele Miraglia , Perrone Laura

Background: IGF1R mutations are characterized by IGF-1 resistance causing impaired fetal and postnatal growth. Several reports in children with heterozygous defects of IGF1R have demonstrated a variable phenotype, which can be associated to microcephaly, dismorphic features and mild developmental delay.Case presentation: We report of an 8-years-old boy, who came at our observation with short stature (−3.2 SDS) and mild microcephal...

Circulating MKRN3 levels in 5 CPP girls with MKRN3 gene mutation

Aiello Francesca , Palumbo Stefania , Cirillo Grazia , Luongo Caterina , Festa Adalgisa , Miraglia Del Giudice Emanuele , Grandone Anna

Background: MKNR3 is a paternally expressed gene whose loss-of-function mutations cause Central precocious puberty (CPP). The precise molecular disruption produced by MKRN3 mutations remains unclear albeit protein structure suggests MKRN3 could play a role in proteasome ubiquitination. Circulating MKRN3 levels has been negatively associated to LH peak, estradiol and kisspeptin in idiopathic CPP and healthy controls. However, no literature data is available for...

PROKR2 in Girls with Idiopathic Central Precocious Puberty

Grandone Anna , Luongo Caterina , Cassio Alessandra , Salerno Mariacarolina , Tornese Gianluca , Festa Adalgisa , del Giudice Emanuele Miraglia , Cirillo Grazia

Introduction: PROKR2 is a 384-amino acid G-protein-coupled receptors (GPCR) that regulates GnRH secretion in the hypothalamus. PROKR2 mutations have been described as cause of a certain percentage of of hypogonadotropic hypogonadism and Kallmann syndrome.In 2017 a heterozygous frameshift gain of function mutation of PROKR2 was identified in a 3.5-year-old girl with central precocious puberty (CPP).The aim of our st...

A New Mutation in IHH Gene Causing Severe Short Stature

Festa Adalgisa , Luongo Caterina , Grandone Anna , Cirillo Grazia , Greco Federica , Torella Annalaura , Nigro Vincenzo , Giudice Emanuele Miraglia Del

Introduction: Heterozygous mutations in IHH are known to cause Brachydactyly type A1 (BDA1), in which the typical clinical features are bilaterally short-ening or absence of the middle phalanges of most digits of hands and feet, shortness of 1st proximal bone and short stature; althougt short stature is considered part of BDA1, in most reported cases is not always present or unrelevant compared to the stature of unaffected relatives. Recently heterozygous mutations ...

Background: The phenotype of SHOX aploinsufficiency is highly variable also in affected members of the same family with broad differences in severity of short stature, disproportion, presence of Madelung deformity.Case presentation: We present a family with a new mutation of SHOX gene. A 2.3 years old girl, born at term from unrelated parents, came to our observation for short stature. Her height was −2.02 SDS, arm span was normal, sitting heigh/he...

Mutation in RTTN, a Regulator of Ciliary Function, Causes a Complex Syndrome Characterized by Severe Congenital Microcephaly, Lissencephaly and Profound Growth Failure in Two Siblings

Grandone Anna , Nigro Vincenzo , Torella Annalaura , Festa Adalgisa , Luongo Caterina , Marzuillo Pierluigi , Coppola Ruggero , del Giudice Emanuele Miraglia , Perrone Laura

Background: Primordial dwarfism (PD) is a phenotype characterized by profound growth retardation and microcephaly that is prenatal in onset. Recently mutations in genes involved in ciliogenesis have been described in patients with primordial dwarfism phenotype. In 2012 mutations in rotatin (RTTN), a protein involved in cilia structure and function, have been described in in individuals with bilateral diffuse polymicrogyria, but not growth failure.Case pr...
