The Polycomb Repressive Complex 1 (PRC1) represses gene expression through CBX2, which binds to H3K27me3 and promotes chromatin expression. Recently, CBX2 has been shown to function in testis-formation by directly repressing Wnt4's downstream target, Lef1, in Sertoli cells rather than positively controlling Sry expression, as previously thought. Here, we describe two new cases carrying missense mutations in CBX2. The first is a female with 46,XY ...

Background: A child with slow growth rate (<−2 SDS) polyuria and polydipsia warrants urgent investigation for hypothalamic–pituitary tumors.Objective and hypoyhesis: To present the case of a boy with slow growth rate, polyuria NAD polydipsia due to remnant craniopharyngeal duct.Method: Boy 11 years old, was evaluated because of short stature and slow growth rate documented for 2 years. He reported no headaches but he...

Background and aims: The aim of this study was to investigate the frequency of diabetic ketoacidosis and diagnostic mistakes in onset diabetes mellitus type l in children and their relationship with age.Materials and methods: In this study were included 269 patients (from 7 month to 17 years) in onset diabetes mellitus type l since 2010–2013. All patients were divided in to two groups. The first group consists of 92 patients (children were younger t...

Background: Newborn screening for CAH is effective in identifying the severe cases; however, the high rate of false-positive (FPR) results remains an important issue. Therefore, positive neonatal results must be confirmed by serum 17OHP levels, which present a great overlap among all forms.Objective and hypotheses: To evaluate the utility of molecular analysis to improve CAH diagnosis in NBS program.Method: Between 1999 and 2014, 8...

Background: Main concerns of Congenital Adrenal Hyperplasia Newborn Screening (CAH-NBS) are the high false-positive results (FPR) rate, low positive predictive value (PPV) and heterogeneity of confirmatory tests. Considering the CAH-NBS implementation in our country, our.Objectives: Objectives are to optimize the Neonatal 17OH-Progesterone (N17OHP) cutoffs and to evaluate the best serum confirmatory test.Methods: 473 983 newborns w...

Background: Adolescence is a critical period of life, and even more if a chronic illness is present like type 1 diabetes mellitus (T1DM). The healthy lifestyle practice is one of the pillars of the T1DM treatment.Objective and hypotheses: To evaluate the association between lifestyle and health related quality of life (HRQoL) in adolescents with T1DM.Method: Lifestyle and HRQoL were evaluated in 69 T1DM adolescents (34 male, mean a...

Background: Hereditary hypophosphatemic rickets with hypercalciuria (HHRH) is a rare autosomal recessive disorder characterized by rickets, muscle weakness, bone pain, nephrocalcinosis or nephrolithiasis. It is caused by mutation in SLC34A3 gene, encoding for renal sodium-phosphate cotransporter IIc (NaPi-IIc).Case: A patient aged 10 years came for evaluation for bone pain at lower limbs. He was born at full term from no...

Introduction: Mandibular hypoplasia, Deafness, Progeroid features, Lipodystrophy (MDPL) syndrome is a rare autosomal dominant disorder caused by mutation in POLD1 gene, which encodes the catalytic subunit of the DNA polymerase delta (Polδ) enzyme.Case: a 6.5-year-old boy presented to the outpatient clinic due to severe thinness (BMI -4.86 SDS, WHO 2006 growth charts). Examination of his medical history rev...

Background: Congenital Adrenal Hyperplasia (CAH) is a rare autosomal recessive genetic disorder caused by the absence or severely impaired activity of enzymes involved in adrenal steroid biosynthesis, with over 90% of cases resulting from 21-hydroxylase deficiency. The initial presentation of CAH can range from a dramatic adrenal crisis with salt loss to more subtle signs such as female genital ambiguity or male scrotal hyperpigmentation. Timely identification...

Background: Pseudohypoparathyroidism (PHP) refers to a group of rare diseases characterized by post-receptor resistance to parathyroid hormone and other protein hormones (TSH, GHRH, LH, FSH), due to defects in the Gsα protein. PHP can be associated with the phenotype known as Albright’s hereditary osteodystrophy (AHO), which includes round face, short stature, brachydactyly, ectopic ossifications and mental retardation. Diagnosis often stem out fro...
