Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder characterized by hypothalamic-pituitary dysfunction. The main clinical features include neonatal hypotonia, distinctive facial features, overall developmental delay, and poor growth in infancy, followed by overeating with severe obesity, short stature, and hypogonadism later in development. This paper reviews recent updates r...
Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder that is caused by the lack of expression of paternally inherited imprinted genes on chromosome 15q11-q13. This syndrome has a characteristic phenotype including severe neonatal hypotonia, early-onset hyperphagia, development of morbid obesity, short stature, hypogonadism, learning disabilities, behavioral problems, and psychi...
Pyridoxine-dependent epilepsy (PDE) was first described in 1954. The ALDH7A1 gene mutations resulting in α-aminoadipic semialdehyde dehydrogenase deficiency as a cause of PDE was identified only in 2005. Neonatal epileptic encephalopathy is the presenting feature in >50% of patients with classic PDE. We report the case of a 13-month-old girl with profound neonatal hypoglycemia (0.6 mmol/L; refe...
Pelizaeus-Merzbacher-like disease 1 (PMLD1) is a slowly progressive leukodystrophy that typically presents during the neonatal or early infantile period with nystagmus, commonly associated hypotonia, delayed acquisition of motor milestones, speech delay and dysarthria. We present 7-year-old female born to nonconsanguineous marriage developmental delay. On examination, she had 22 teeth, nystagmu...
BACKGROUND Peroxisomal disorders are classified in two major groups: (1) peroxisome biogenesis disorders and (2) single peroxisomal enzyme/transporter deficiencies. D-bifunctional protein deficiency (OMIM #261515) is included in this last group of rare diseases and leads to an impaired peroxisomal beta-oxidation. D-bifunctional protein deficiencies are divided into four types based on the degre...
Case presentation: 9-year-old female, born at term by vaginal delivery without complications. Referred to the neurologist due learning difficulties and gait imbalance. She was with mild hypotonia, presenting difficulty in breastfeeding, but did not need any ventilatory support. diagnosed congenital clubfoot which successfully treated until age of 2 years 4 months. Extended screening for inborn ...
The aim of this study was to characterize the clinical and genetic features of a 4-year-old female with merosin-deficient congenital muscular dystrophy type 1A (MDC1A). MDC1A is the most common form of congenital muscular dystrophy. MDC1A is caused by mutation of the laminin α-2 gene (LAMA2), localized to chromosome 6q22-23. Clinical presentation, as well as the results of neuro-imaging, electr...
