Genetic Variant in a Patient with Epilepsy, Ophthalmological Anomalies, and Neurodevelopmental Delay.

We present the findings of a Whole Exome Sequencing in a 2-year-old boy, conceived via Fertilization with donor sperm, who suffers from an undiagnosed neurological syndrome. The following heterozygous variant in the gene was identified and classified as likely pathogenic: c.1655_1656, p.

First results of the growth disorders related twinning programme Partners4Growth implemented at the tertiary university pediatric endocrinology clinics in Bulgaria.

Objectives: Early diagnosis of childhood growth disorders, their timely and proper treatment are important for better outcomes.The aim of the present study was to assess the results of the first 18 months of the growth disorders related twinning programme "Partners4Growth" implemented at all tertiary university pediatric endocrinology clinics in Bulgaria.

Methods: In 2019, Partners4Growth started operation at 7 centres (4 experienced and 3 twin centres) with the main aim of aligning their practices in the shortest possible time.

Dopa-responsive dystonia in Bulgarian patients: report of three cases.

Dopa-responsive dystonia (DRD) comprises a group of rare autosomal inherited neurotransmitter disorders characterized with childhood or adulthood onset. We report three cases of DRD. Two boys (1.

Comprehensive Genetic Evaluation of Bulgarian Children with Syndromic Craniosynostosis.

Syndromic craniosynostosis (SC) is a genetically determined premature closure of one or more of the cranial sutures, which may result in severe dysmorphism, increased intracranial pressure along with many other clinical manifestations. The considerable risk of complications along with their significant incidence makes these cranial deformations an important medical problem. Aiming to elucidate the complex genetic etiology of syndromic craniosynostosis, we investigated 39 children, screened systematically with a combination of conventional cytogenetic analysis, multiplex ligation-dependent probe amplification (MLPA) and array-based comparative genomic hybridisation (aCGH).

Arginase deficiency in Bulgaria: first cases and potential endemic region for the disorder.

Arginase deficiency is an autosomal recessive urea cycle disorder caused by pathogenic variants in the gene. The clinical features of the disease include spasticity, tremour, ataxia, hypotonia, microcephaly and seizures. Growth delay can also be observed in the affected individuals.
