چکیده
A syndrome of holoprosencephaly and postaxial polydactyly, associated with hydrocephalus, heart defect, adrenal hypoplasia, and other visceral malformations, has been observed in five unrelated children with normal chromosomes. Clinical overlap with lethal acrodysgenital dwarfism (SmithLemli-Opitz syndrome type II) and hydrolethalus syndrome is discussed. Recessive inheritance

Holoprosencephaly-polydactyly ('pseudotrisomy 13') syndrome: a syndrome with features of hydrolethalus and Smith-Lemli-Opitz syndromes. A collaborative multicentre study.
A syndrome of holoprosencephaly and postaxial polydactyly, associated with hydrocephalus, heart defect, adrenal hypoplasia, and other visceral malformations, has been observed in five unrelated children with normal chromosomes. Clinical overlap with lethal acrodysgenital dwarfism (Smith-Lemli-Opitz syndrome type II) and hydrolethalus syndrome is discussed. Recessive inheritance seems likely.
متن کاملPseudotrisomy 13: clinical findings and genetic implications.
The combination of holoprosencephaly, postaxial polydactyly, and normal karyotype has been termed pseudotrisomy 13 syndrome. Here, we report the prenatal diagnosis of pseudotrisomy 13 in three siblings suggesting autosomal recessive inheritance of this syndrome. Clinical overlap with hydrolethalus syndrome, Smith-Lemli-Opitz syndrome, Meckel syndrome, and Pallister-Hall syndrome is discussed.
متن کاملHoloprosencephaly and polydactyly: a possible expression of the hydrolethalus syndrome.
We report two fetuses with hydrocephalus, features of holoprosencephaly, and postaxial polydactyly born to a consanguineous Mexican-American couple. The phenotype is consistent with the hydrolethalus syndrome, although holoprosencephaly has not previously been seen in this condition. We believe other similar cases with a trisomy 13 phenotype but normal chromosomes may also have the hydrolethalu...
متن کاملThe Association of Common Atrium with Smith-lemli-opitz Syndrome in an Infant
Smith-Lemli-Opitz syndrome is a rare syndrome presenting with multiple congenital anomalies/mental retardation associated with low plasma cholesterol levels. The spectrum of severity extends from prenatal death with holoprosencephaly or other lethal malformations, to patients with minimal physical abnormalities and normal intelligence or minimal intellectual impairment. Congenital heart defect ...
متن کاملTrends in prenatal diagnosis of non-specific multiple malformations disorders with reference to the own experience and research study on Smith-Lemli-Opitz syndrome.
AIM OF THE STUDY Biochemical diagnosis of fetuses with multiple malformations--an attempt to determine the frequency of prenatal Smith-Lemli-Opitz syndrome. Discussion on trends in prenatal diagnosis of non-specific multiple malformations disorders. MATERIAL AND METHODS A total of 117 fetal samples were obtained. They were analyzed with gas chromatography/mass spectrometry (GC/MS) method to a...
