Wolf–Hirschhorn (4p-) syndrome with West syndrome
Wolf-Hirschhorn syndrome (WHS) is a chromosome disorder (4p-syndrome) which is characterized by craniofacial features and epileptic seizures. Here, we report a case of WHS with West syndrome, in whom the seizures were refractory to several antiepileptic drugs but were responsive to the addition of lamotrigine. The patient had epileptic spasms at age seven months. The interictal electroencephalo...
متن کاملUnusual 4p16.3 deletions suggest an additional chromosome region for the Wolf-Hirschhorn syndrome-associated seizures disorder.
OBJECTIVE Seizure disorder is one of the most relevant clinical manifestations in Wolf-Hirschhorn syndrome (WHS) and it acts as independent prognostic factor for the severity of intellectual disability (ID). LETM1, encoding a mitochondrial protein playing a role in K(+) /H(+) exchange and in Ca(2+) homeostasis, is currently considered the major candidate gene. However, whether haploinsufficienc...
متن کاملPrenatal diagnosis of Wolf-Hirschhorn syndrome (4p-) in association with congenital hypospadias and foot deformity
BACKGROUND: Wolf-Hirschhorn syndrome is caused by distal deletion of the short arm of chromosome 4 (4p-). We report a case in which intrauterine growth restriction, hypospadias and foot deformity were detected by prenatal ultrasound examination at 29 weeks of gestation. CASE PRESENTATION: A 31-year-old gravida 2 partus 1 woman was referred at 29 weeks' gestation with suspicion of intrauterine g...
متن کاملWolf-Hirschhorn syndrome.
Chromosomal abnormalities are important cause of mental retardation and congenital anomalies. We report a case of a rare chromosomal disorder, Wolf-Hirschhorn syndrome, caused by deletion of short arm of chromosome 4. It was characterized by well-described facial appearance, seizures, microcephaly and midline closure defects along with growth and mental retardation.
متن کاملFamilial Wolf-Hirschhorn syndrome resulting from a cryptic translocation: a clinical and molecular study.
We present three cousins who have normal karyotypes, despite having clinical features of Wolf-Hirschhorn syndrome. Fluorescence in situ hybridisation techniques confirmed that all three relatives were monosomic for the distal short arm of chromosome 4 and that a cryptic translocation involving chromosomes 4 and 11 was segregating within the family. Segregation analysis indicated that the risk o...
