Partial trisomy 3q causing mild Cornelia de Lange phenotype.
A brother and sister are reported with developmental delay and facial features suggestive of the Cornelia de Lange syndrome. Cytogenetic analysis showed them to be trisomic for the region 3q25.1-26.2 because of the inheritance of an unbalanced interchromosomal insertion from their father, who was a balanced insertion carrier. The clinical phenotype and cytogenetic analysis (including chromosome...
متن کاملPartial trisomy 3q and the mild Cornelia de Lange syndrome phenotype.
et al,5 respectively. To identify the IVS 1 (-13T-*G) mutation, two PCR primer sets were designed, based on the amplification refractory mutation system (ARMS) described by Newton et al.6 The first set amplifies specifically the wild type allele, the second set the IVS1(-13T-G) allele (figure). The frequencies of the three mutant alleles are given in table 1. Our data confirm those of Huie et a...
متن کاملBehavioural phenotype of Cornelia de Lange syndrome.

Cornelia de Lange syndrome (CdLS) is a rarely seen multisystem developmental disorder syndrome characterized by facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, growth and cognitive retardation, and gastrointestinal abnormalities. We present here a case of newborn ma...
متن کاملDe novo duplication 3q in an infant with a vascular ring and features overlapping Cornelia de Lange phenotype
Partial duplication of chromosome 3q is a recognizable syndrome with characteristic facial features, microcephaly, digital anomalies, genitourinary and cardiac defects as well as growth retardation and developmental delays. While there is clinical overlap with the unrelated Cornelia de Lange syndrome (CDLS), there are distinguishing features and molecular etiologies. Most cases of 3q duplicatio...
