Aim and Method: Achondroplasia is the most common form of short-limbed dwarfism, characterized by mutations in the FGFR3 gene. Vosoritide, a C-type natriuretic peptide analog, has shown promise in promoting linear growth in children with achondroplasia. This study aims to present the real-life experiences of using vosoritide in children diagnosed with achondroplasia.Method and Results: A prospective study was conducted o...

Tugba Canbaz Aylin , Helvacioglu Didem , Gurpinar Tosun Busra , Yavas Abali Zehra , Sahin Yener , Guran Tulay , Bereket Abdullah , Dagcinar Adnan , Turan Serap

Background/aims: Pilocytic astrocytomas (PA) are low-grade neoplasms that affect the precortical visual pathway and are most commonly detected in children and adolescents, representing 2–5% of childhood central nervous system (CNS) tumours. Optic gliomas (OPGs) can occur sporadically, or in association with neurofibromatosis type 1 (NF1). We assessed the prevalence of endocrine dysfunction in children with PA and evaluated outcomes between subgroups of P...

Background: Human peroxisomal fatty acyl CoA oxidase 1, encoded by the ACOX1 gene, catalyzes the first and rate limiting step in the beta oxidation of straight chain fatty acids in the peroxisomes. Biallelic mutations in ACOX1 are associated with pseudo-neonatal adrenoleukodystrophy characterized by severe hypotonia, seizures, psychomotor retardation followed by neuroregression, and death in early childhood. To date, primary adrenal insuffici...

Down syndrome (DS) is the most common chromosomal disorder in live births (1/1500-1/700) and caused by a meiotic nondisjunction (trisomy 21). DS is associated with an increased risk of thyroid disorders in addition to other systemic problems. In this study, we aim ed to investigate the thyroid hormone profiles and associated autoimmune diseases in DS.Material and Method: DS patients, aged 0-18 years, who were followed for thyroid problem...

A Novel Founder Mutation of CYP21A2 in Patients with CAH due to 21-Hydroxylase Deficiency

Okten Aysenur , Karaguzel Gulay , Toraman Bayram , Kalay Ersan , Dincer Tugba

Background: Mutations in CYP21A2 are the most common cause of congenital adrenal hyperplasia (CAH). Even though disease linked mutations are rarely classified as founder, in this study, we describe a novel founder mutation, c.2T>C (p.M1?), inactivating the translation initiation codon.Objective and Hypotheses: We aimed to investigate genotype–phenotype correlation and population based origin of this novel mutation in CAH patients with 2...

Background and Objectives: Enlargement and cystic changes in ovaries of patients with longstanding overt hypothyroidism has been observed in numerous case reports. But there is limited data about the effect of subclinical hypothyroidism (SH) on ovarian volume and ovarian cyst formation. We evaluated the relationship between serum thyroid stimulating hormone (TSH) level and ovarian volume and sonographic appearance in prepubertal girls with SH.<p class="abs...

45,X/47,XYY mosaicism is quite rare, and, like 45,X/46,XY, it can be associated with mixed gonadal dysgenesis, Turner syndrome or apparently normal male/female phenotype. An infant aged 16 days, born full-term via spontaneous vaginal delivery to a 32 year-old G1P1 woman. His pregnancy and perinatal period were both uncomplicated except for maternal long QT syndrome. There was third degree cousin consanguinity between the parents. There was no any virilizing drug use and no mat...
