Background: The isodicentric Y (idic Y) is one of the most common aberrations of the Y chromosome. Most patients (pts) are chromosomal mosaics, including 45,X cell line.Objective and hypotheses: Our aim is to describe clinical and molecular features of our 45,X/46,Xidic(Y) cases.Method: We retrospectively evaluate the clinical description of nine cases (six females, one male, two with ambiguous genitalia) with mosaic karyotype 45,X...

Background: Thyroid dysgenesis has been considered a sporadic disease, but recent observations suggested a possible genetic basis.Objective and hypotheses: The aim of our report is to evaluate the incidence of hormonal and ultrasound thyroid anomalies in siblings of CH patients with thyroid dysgenesis.Method: In Emilia-Romagna Region (Italy) 328 CH infants were diagnosed by neonatal screening between January 2000 and December 2012....

Background: Final height (FH) in patients (pts) with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is often under the genetic target, despite improvement of new therapeutic strategies.Objective and hypotheses: The aim of this study is to evaluate FH in a cohort of pts with CAH due to 21OHD diagnosed before and after newborn screening (NBS) era in Emilia-Romagna, Italy.Method: We evaluated final heigh...

Background: Skeletal dysplasias are characterised by bone-cartilage involvement and impairment of growth and body proportions. Reports of the benefits of GH treatment are difficult to evaluate for the small number of subjects, short period of treatment, few final height (FH) data in groups with and without GH deficiency (GHD).Objective and hypotheses: The aim of our study was to assess FH and body proportions in pts with skeletal dysplasia and GHD.<p...

The pathogenetic role of genetic factors in congenital hypothyroidism (CH) is now widely known. The constant evolution of diagnostic methods in the field of medical genetics provides the opportunity to obtain an etiological diagnosis in CH patients with genetic defects in candidate genes. We performed genetic analysis by Next Generation Sequencing (NGS) of 18 candidate genes (DUOX2, DUOXA2, FOXE1, GLIS3, IGSF1, IYD, NKX2-1, NKX2-5, PAX8, SLC16A2, SLC26A4, SLC5A5, TG, THRA,...

Short stature is a common clinical presentation in children. New genetics approache such as “Next Generation Sequencing” have recently reported many monogenic defects in genes related to the growth plate cartilage and in GH-IGF-1 axis. The purpose of this study was to analyze a cohort of 64 patients (31 females and 33 males) affected by ISS. The patiens have been subjected to genetic investigations by performing an NGS panel of genes involved in growth, the evaluat...

Introduction: Short stature is one of the main reasons leading a patient to the attention of the Pediatric Endocrinologist. It is important to know the possible causes of short stature, even the rarest genetic mutations associated with short stature. Although the diagnosis of short stature is primarily the result of physical examination with anthropometric measurements, biochemical and radiological data, genetical tests currently play an important role.<p ...

V.C. was referred to our Centre for short stature. The mid-parental target height was 153 cm (-1,6 SDS). Her mother had one spontaneous abortion and displayed mild short stature (151,5 cm). Her father had Arnold Chiari syndrome type 1 and was 165,9 cm tall. V.C. was delivered at term after in-vitro-fertilization pregnancy with intrauterine growth retardation (IUGR) from gestational week 21. Birth weight was 2160 g (SGA, SDS -3,17); length was 45 cm (SDS -2,92); head circumfere...

We report rhGH-treatment results in a 14-yrs-old SGA patient with spondylo-epi-metaphyseal chondrodysplasia. The patient carries a rare de novo eterozygous variant of COLA1 (c.1510G>A, P.Gly 504Ser) associated with a rare AD spondylo-epiphyseal dysplasia. Born at term after olygohidramnios-complicated pregnancy, SGA for weight and lenght, the patient has showed a post-natal reducing growth with regular cognitive development. At the age of two height was -4 SDS, with parenta...

Short stature is a frequent disorder in the pediatric population caused by multiple possible reasons. One of them it can be the mutation of the ACAN gene, with an autosomal dominant transmission, which also correlates with accelerated bone maturation and early osteoarthritis up to bone dysplasia. A 10.8-year-old patient came to our observation for poor statural growth (125.8 cm, -2.6 SDS) with a parental target of 150.4 cm +/- 8 cm (-2 SDS), on Triptorelin braking therapy, sin...
