Background: The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase deficiency, which in its severe form can cause genital ambiguity in females. This can be ameliorated by administering dexamethasone to the mother.Case: This is a family whose index case is a first son diagnosed by Madrid Newborn Screening Program of CAH with salt-wasting form due to 21-hydroxylase deficiency. Mutation analysis revealed: ‘hybrid deletion’ ...

Background-Aim: Gene rearrangements between CYP21A2, TNXB and their homologous pseudogenes (CYP21A1P,TNXA) result in chimeric genes, responsible for the CAHX syndrome. CAHX patients show CAH and Ehlers-Danlos syndrome (EDS) symptoms. Three CAHX chimeras with different clinical severity are described: CH1 (including 120bp deletion in exon 35), CH2 and CH3. The small size and few series reported so far warrant further studies ...

Background-Aim: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroidogenic pathway of the adrenal cortex. In their most severe forms, they produce adrenal insufficiency and virilization of external genitalia when involving the terminal enzymes of the cortisol and aldosterone synthesis pathway (21-hydroxylase (21-OHD, OMIM#201910) and 11-hydroxylase (11-OHD, OMIM#202010) deficiencies). Mutations of <e...

Background: The nonclassic congenital adrenal hyperplasia (CAH) is often presented as isolated premature pubarche in childhood. Definitive diagnosis is genetic.Objective and hypotheses: To describe patients diagnosed in our hospital, clinical signs and laboratory results that lead to genetic study. To analyze adult height.Method: Descriptive retrospective study of our population with genetic confirmation.Resu...

Introduction: Fanconi anemia (FA) is a rare genetic disease that presents with aplastic anemia. Around 60% have short stature (SST), with a mean height of -2.2 SD. However, studies assessing the etiology of SST not having reached relevant conclusions.Aim: Our aim was to evaluate the clinical features and endocrine status in relationship to SST in patients with FA.Methods and Patients: A cross-secti...

Introduction: Fanconi anemia (FA) is a genomic instability syndrome associated with congenital abnormalities. Structural anomalies of the central nervous system (CNS), particularly a small pituitary gland, have been published in a few case series. This has been thought to be the cause of the short stature (SS) observed in FA.Methods: A cross-sectional exploratory study was carried out in pediatric patients at the FA Span...

Introduction: Childhood obesity means a Public Health problem. It is related to chronic diseases in adults, a decrease in quality of life, and an increase in social and sanitary costs. In Spain, the National Health Service (ENSE 2017) stood the prevalence of overweight in toddler between 2 to 7 years old, in 18,26% and obesity in 10,30%, no differences between sex. In 2015 the prevalence of overweight and obesity in childhood are 21, 3 % and 6, 2 &...

Introduction: 2020 ESPE guidelines recommend early reevaluation in primary congenital hypothyroidism (PCH) with thyroid in situ (TIS) and with levothyroxine dose lower than 3 mg/kg/day.Materials and Methods: Our Congenital Hypothyroidism screening program determine TSH and TT4 in dried blood spot (DBS) at 48 hours of life. A second DBS (DBS2) is indicated when the first is positive. Multicenter retrospective study (05/2016-05/2020; 105...

Objective: Analyze CCH detection program results from 3 Autonomous Communities: TSH and total T4 (TT4) in dried blood spot (DBS) at initial screening (48 hours of life) and at retesting. Describe the characteristics of neonates with screening compatible with CCH. Consider whether TBG deficiency (TBGD) is an added difficulty in said study.Materials and Methods: Retrospective study (May 2016-May 2020) of all neonates ≥33 weeks and/or ≥1500 gr...
