Microdeletion 1q44 on the long arm of chromosome 1 leads to a phenotype that includes microcephaly, seizure, agenesis or hypogenesis of the corpus callosum, polydactyly, congenital heart defects and severe developmental delay along with characteristic facial dysmorphic signs. Until today, the
A 4-year-old Saudi female child with extreme failure to thrive, striking dysmorphic features, developmental delay, congenital hypoparathyroidism, UTI, seizures, chronic otitis media, chronic non-specific gastroenteritis and repeated life-threatening infections was followed from birth. She was the
Menkes disease is a rare sex-linked disorder of copper metabolism, characterized with several multiple organ dysfunctions. It is frequently associated with seizure disorders, mental retardation, and urologic abnormalities. It may also have some serious respiratory complications, such as upper airway
An infant is reported who presented with a de novo 21;21 translocation trisomy 21 and an atypical phenotype for Down syndrome (DS). Findings included microcephaly, small stature, downslanting palpebral fissures, absent Brushfield spots, moderate micrognathia, left ptosis, left torticollis, severe
Desmosterolosis is a rare autosomal recessive disorder of elevated levels of the cholesterol precursor desmosterol in plasma, tissue and cultured cells. With only two sporadic cases described to date with two very different phenotypes, the clinical entity arising from mutations in
Mutations in PIGN, resulting in multiple congenital anomalies-hypotonia-seizures syndrome, a glycosylphosphatidylinositol anchor deficiency, have been published in four families to date. We report four patients from three unrelated families with epilepsy and hypotonia in whom whole exome sequencing
BACKGROUND
Severe prolonged hypocalcemia may occur in neonates whose parathyroid hormone production has been blocked by maternal hyperparathyroidism. This report describes such a case.
METHODS
A 7 day-old girl was admitted suffering from dyspnea and repeated convulsions that had continued for 2
Owing to the large size of chromosome 2, partial monosomy of the long arm of this chromosome gives rise to many specific phenotypes. We report on a 2-month-old girl with an interstitial deletion of 2q24.2q24.3, which was confirmed by microarray-based comparative genomic hybridization analysis. The
An 8 year old boy with ring chromosome 21 who was susceptible to sinorespiratory infections due to hypogammaglobulinaemia is reported. He presented with the characteristic features of monosomy 21 syndrome, such as psychomotor retardation, hypertonia, large saccular ears, prominent nasal bridge,
The deletion of the distal long arm of chromosome 1 is associated with a characteristic facial appearance and a pattern of associated malformations. Characteristic manifestations include a round face with prominent 'cupid's bow' and downturned corners of the mouth, thin vermilion borders of lips, a
Multiple congenital anomalies and craniofacial dysmorphism are characterizing the so-called Emanuel or supernumerary der(22)t(11;22) syndrome (OMIM609029). Mental and developmental retardation are major clinical features. The der(22) may arise from a parental balanced t(11;22)(q23;q11.2) or can be
Sixteen cases of terminal deletions and 17 cases of interstitial deletions of the long arm of chromosome 7 have been reported to date. We present two new cases of the former and three of the latter. The somatic changes in these patients are tabulated and an update on the anomalies associated with
A dysmorphic boy with severe mental retardation was found on array CGH to have an insertional translocation of chromosome 16p13.3 into the short arm of chromosome 22, karyotype 46,XY,.ish der(22),ins(22;16)(p13;p13.3p13.3) de novo. His clinical features overlap with the reported cases of
We describe a small, term, male infant with corticospinal tract aplasia secondary to motor cortex dysplasia from a neuronal proliferation and/or migrational defect. The infant also had microdolichocephaly, sloping forehead, hypertelorism, flat nose, apparently low-set ears, micrognathia,
We report on a 12-year-old girl presenting with mental retardation, trigonocephaly, midface hypoplasia, upward-slanting palpebral fissures, arched eyebrows, bilateral epicanthal folds, hypertelorism, a flattened nasal bridge, a short nose, anteverted nares, a long philtrum, a small mouth,
