Introduction: Growth restriction (GR) comprises ~50% of new patient referrals to paediatric endocrine clinics with <20% receiving a clear diagnosis. Enhanced genetic testing and stratification leading to tailored clinical care is a fundamental need. Whole-genome sequencing (WGS) was offered to patients recruited to the 100,000 Genomes Project (100 KGP), leading to new diagnoses in ~25% of all rare disease participants. The analysis pipeline uses disease-spe...

Introduction: Sitosterolaemia, is a rare autosomal recessively inherited condition. The incidence in the literature varies hugely between 1/200,000 and 1 in one million. Its incidence is likely underestimated as it is commonly misdiagnosed as familial hypercholesterolaemia. Sitosterolaemia tends to present earlier, with xanthomas, joint pains and very high total cholesterol and LDL. Routine lipid testing does not include specific testing for plant sterols. Onc...

Background: Duchenne muscular dystrophy (DMD) is caused by mutations in the dystrophin gene and results in a progressive muscular damage and degeneration. Endocrine complications result from decreased energy expenditure, immobility and glucocorticoid (GC) treatment. Due to the multidisciplinary management and emerging genetic and molecular therapies longer survival is expected and there is an increasing emphasis on the quality of life in DMD. Aim of the study ...

Introduction: Klinefelter syndrome (KS) is a form of aneuploidy resulting from 2 or more X chromosomes in a male. The most common karyotype is 47, XXY. KS affects physical and intellectual development to varying degrees, commonly causing hypo-development of secondary sexual characters and high stature.Case Report: JLV, male, 3 year 1 month age, the first child of a young non-consanguineous couple, was referred to the ped...

Background: Growth is a complex process influenced by several genetic factors both pre and postnatal, in which 80% of the height variation is explained by genetic factors. Nevertheless, the standard medical evaluation of short stature (SS) relies upon physical examination and laboratory parameters and identifies a pathological cause of SS in 1–40% of individuals. Recent advances in genetic diagnosis are revolutionizing the clinician’s ability to obtain a molecular di...

Background: Anti-Mullerian hormone (AMH) concentration is now well studied for prepubertal boys (Plotton, 2009, 2012) or women in reproductive medicine, but there is few data about reference value in newborns. This dosage could be helpful for the management of disorders of sex development.Objective: The objective was to determine reference values of AMH on umbilical cord blood and to compare the values to DSD new born diagnosed during the evaluation....

Background: Most individuals with neonatal hypothyroidism present clinically asymptomatic or with few symptoms. Early treatment with oral levothyroxine prevents complications related to this disorder. We report a case of a male infant with Short Bowel syndrome (SBS) and congenital hypothyroidism (CH) treated with rectal levothyroxine.Case and presentations: A male patient with previous gastroschisis underwent multiple surgical approaches for small bowel ...

Background: In total of 48,XXYY Syndrome occurs in 1:20.000–1:50.000 male births. It used to be considered as a variant of Klinefelter syndrome, but now it is considered as a distinct clinical and genetic entity with increased risks for congenital malformations, additional medical problems and more complex psychological and neurodevelopmental involvement. 48,XXYY Syndrome results from the fertilization of a normal female oocyte (Xm), with an aneuploid sperm (XpYpYp) produ...

Background: Determination of steroids in amniotic fluid (AF; Forest et al., J Clin Endocrinol Metab, 1980) has been essentially used in the three past decades for the prenatal diagnosis of 21-OH deficiency. With the recent advances of ultrasound technology (US) and the widespread use of amniocentesis, prenatal diagnosis of DSD appears more common especially if a mismatch between karyotype and external genitalia detected by US occurs. An accurate and specific ...

Background and Aims: Turner Syndrome (TS), 45X0, is the most common chromosomal pathology affecting females, occurring in 1:2500 to 1:5000 female infants. The typical phenotype includes short stature, gonadal dysgenesis leading to sexual infantilism, low-set ears, low rear hairlin, mamary hypertelorism, neck webbing, gothic palate, irregular rotation of the elbows, shield chest, shortening of the 4th metacarpal, low hairline, shortening of lower extremities, renal disorders a...
