Background: Congenital hypogonadotropic hypogonadism (CHH) is a rare disease with a complex clinical picture and genetic background. In up to 50% genetic mutations are found. The goal is to be able to provide a comprehensive prognosis and genetic counseling for this family with CHH.Case presentation: At the age of 16 years a boy with familial constitutional delay (adrenarche only with 15 years, no growth spurt, bone age 14 years) present...

Septo-optic dysplasia (SOD) is a rare congenital disorder characterized by a classic triad of optic nerve hypoplasia, agenesis of septum pellucidum and corpus callosum, and hypoplasia of the hypothalamic-pituitary axis. Up to date, a shared consensus is not available and the diagnosis relies mainly on clinical and neuroradiological findings. Even though few genes have been described as responsible for this syndrome, the precise causes of SOD remain unknown and a combination of...

We described a family in which MODY-GCK was detected in 6 people and its course varied.Materials and methods: The diagnosis of GCK-MODY was verified by the proband and his relatives on the basis of direct automatic sequencing and sequencing by Sanger.Results: Proband – a boy of 12 years, diabetes mellitus (DM) type 1 is diagnosed at the age of 11 years. He felt polydipsia, polyuria. Body weight was normal, he has not any disea...

Pituitary gigantism is a rare disorder caused by excess of GH/IGF-1 due to GH-secreting lesions, that occurs before epiphyseal closure leading to increased linear growth. These cases have more aggressive features of pituitary disease than sporadic acromegaly, including a younger age at disease onset and larger tumor size, and they can be challenging to treat. Over the past two decades several molecular defects that cause GH-secreting pituitary adenomas have been identified, in...

The main role of the acid-labile subunit (ALS) is to stabilize the IGFBP3/IGF complexes. Pathogenic variants in the gene coding for ALS (IGFALS) results in IGF1 and IGFBP3 deficiency, short stature, delay puberty and insulin resistance. The aim of these study was to identify the genetic cause in a patient with suspected ALS deficiency. The proband is the third son of non-consanguineous parents, evaluated for the first time at 17.3 years due to short stature (−2....

Background: Resistance to thyroid hormone (RTH) is a dominantly inherited rare disorder (1:40000) mainly due to mutations in the THRB gene that lead to a decreased end-organ responsiveness to thyroid hormone. Clinical and molecular characteristics of four patients with RTH are described.Patients and methods: Four patients from three non-related families were studied; two boys (8.3 and 9.2 years old) and 2 adults (35 year old male and 27 year old...

Background: Pheochromocytoma is an uncommon tumor, producer of Catecholamines and causing hypertension in childhood. It is associated to genetic alterations, generally related with RET gene disorders.Method: We present the case of a unilateral familial isolated pheochromocytoma, present in father and son, carriers of a heterozygous mutation in the VHL gene (c.235C > G; p.R79G).Case: Male, 9 years-old with history of fever, prof...

Background: Mutations in the SUR1 subunit of the KATP channel encoded by the ABCC8 gene can result in diverse phenotypes ranging from Transient Neonatal Diabetes (TNDM) to type 2 diabetes in adulthood. These patients may benefit from sulphonylurea treatment.Objective and hypotheses: To describe the course of diabetes in two families with ABCC8 gene mutations and to assess the effect of sulphonylurea treatment.<p class="ab...

Background: Alström Syndrome (ALMS), occurred due to mutations in ALMS1 gene, is a rare otosomal ressesive disorder. Seven hundred cases have been reported so far. Main clinical findings are rod con dystrofy, neurosensorial deafness, obesity and type 2 diabetes. Hypogonadism, hypothyroidism, growth hormone deficiency, hipertryglyceridemia, cognitive dysfunction, cardiomyopathy, renal, hepatic and pulmoner disorders could also be seen.Objective and h...

Background: Williams Syndrome (WS) is a multisystemic genetic syndrome, which includes characteristic appearance of “elfian face”, growth retardation, mild mental retardation, hypersociality, infantile hypercalcemia, and other endocrine, cardiovascular, and urinary abnormalities. WS is caused by the microdeletion of chromosome 7q11.23; it is usually sporadic but rare autosomal dominant familial cases have been reported in the literature. We present a boy and his moth...
