Deletions on the short arm of chromosome 4 cause Wolf-Hirschhorn syndrome (WHS) and Pitt-Rogers-Danks syndrome (PRDS). WHS is associated with severe growth and mental retardation, microcephaly, a characteristic facies and congenital malformations. The PRDS phenotype is similar to WHS but generally less severe. Seizures occur in the majority of WHS ...

The 22q11 deletion syndromes are a group of conditions in which a characteristic spectrum of congenital cardiac defects may be associated with a wide range of noncardiological congenital anomalies. These syndromes are all linked by a deletion in the long arm of chromosome 22. Although it is a large deletion, ...

Hormonal disorders are common in patients with a 22q11.2 deletion. While hypoparathyroidism was the first endocrine disturbance documented in the DiGeorge syndrome, growth hormone deficiency, hypothyroidism, and hyperthyroidism are now known to occur in patients with a 22q11.2 deletion. This review briefly summarizes our current understanding of the spectrum of ...

Fanconi's anemia can be associated with growth retardation. We describe biologic growth hormone deficiency, isolated or associated with thyrotropin abnormality, and pituitary stalk interruption syndrome on magnetic resonance imaging of 5 patients with Fanconi's anemia. Growth hormone treatment produced catch-up growth in all cases. These findings suggest a common genetic ...

Lack of data on the genotype-phenotype relationship in cases of AZF microdeletions is due to the limited number of histological investigations in human male infertility cases. We investigated the possibility of retrospective detection of Yq11 microdeletions by using DNA extracted from diagnostic testicular biopsies. We used histological criteria to select ...

We report the case of a 7-year old girl with Høyeraal-Hreidarsson syndrome (HHS) and review other cases of HHS. In addition to the previously described important signs of HHS, i.e., prenatal growth retardation, microcephaly, psychomotor retardation, progressive pancytopenia, immunological abnormalities, and cerebellar hypoplasia and ataxia, we consider that delayed myelination ...
Vielhaber S - - 2000
We report the case of a 29-year-old male patient with cerebellar ataxia of Holmes' type. The combination of progressive cerebellar ataxia and hypogonadotrophic hypogonadism is a rare distinctive syndrome which was first described by Holmes in 1907.

Lesch-Nyhan syndrome is a genetic disorder resulting in hyperuricemia, choreoathetosis, mental retardation, and self-mutilation. The most salient feature of this disorder is the self-injurious behavior (SIB). Although the utility of behavioral interventions with SIB has been well documented, behavioral interventions with Lesch-Nyhan syndrome have been limited in number and long-term ...
Smithson S F - - 2000
We report on two boys with a combination of short stature, a broad face, macrodontia and developmental delay. These features suggest that they have the KBG syndrome, a rare but distinctive phenotype.
