Classic Rett Syndrome (RS) is a neurodevelopmental disorder due to mutations in the MECP2 gene in Xq28. Atypical RS with severe early-onset encephalopathy and therapy-resistant epilepsy can be due to mutations in the CDKL5 (Cyclin-Dependent Kinase-like 5) gene in Xp22. We here report a 14-year-old female with a RS-like clinical picture, and well-controlled(More)
Sotos syndrome is characterized by tall stature, advanced bone age, typical facial abnormalities, and developmental delay. The associated gene is NSD1. The study involved 22 patients who fulfilled the clinical criteria. Phenotypic characteristics, central nervous system findings, and cardiovascular and urinary tract abnormalities were evaluated.(More)
BACKGROUND Mutations in the MECP2 gene (methyl-CpG-binding protein-2) are responsible for 60-95% of cases of Rett syndrome (RTT), an X-linked dominant neurodevelopmental disorder affecting mostly girls. Classic RTT is characterized by normal early development followed by psychomotor regression and onset of microcephaly, although variant forms are also(More)
FOXG1 gene mutations have been associated with the congenital variant of Rett syndrome (RTT) since the initial description of two patients in 2008. The on-going accumulation of clinical data suggests that the FOXG1-variant of RTT forms a distinguishable phenotype, consisting mainly of postnatal microcephaly, seizures, hypotonia, developmental delay and(More)
Spinal muscular atrophy (SMA) is a neuromuscular autosomal recessive disease characterized by progressive muscle weakness and atrophy combined with motor neuron degeneration caused by mutations in the SMN 1 gene locus (5q11.2-13.2). Rett syndrome (RS) is an X-linked dominant neurodevelopmental disorder caused by mutations in MECP2 (Xq28) and characterized(More)
