|Brief Title ICMJE||Tissue Specimen Collection for Study of Inherited Diseases Involving Non-muscle Gene Mutations|
|Official Title ICMJE||Mutations in Genes Associated With Pentalogy of Cantrell or Non-Muscle Myosin II Syndromes|
This study will collect blood, urine, and other tissue samples from patients with Pentalogy of Cantrell and other inherited diseases that involve mutations in non-muscle myosin genes. Pentalogy of Cantrell is a very rare disorder in which patients have a combination of severe defects of the middle of the chest including the sternum (breastbone), diaphragm, heart, and abdominal wall. The defect is apparent before birth or at birth. If the mutant gene is identified in the patient tissue samples will also be collected from relatives of the patients.
Participants undergo a medical evaluation that may include a medical history routine blood tests, urine collection, chest x-ray, and electrocardiogram. In addition, blood and urine samples are collected for protein and gene studies. The blood is drawn through a very small needle placed in an arm vein. Children may choose to have a buccal (cheek) sample taken instead of blood draw. Buccal samples can be collected by a cheek swab, in which a soft brush is rubbed on the inside lining of the mouth, or by having the child hold a tablespoon of mouthwash in his or her mouth for a full minute and then spit the mouthwash into a container.
Other tissue samples may be collected from patients at the time of any surgical procedure that may be required as part of their general medical care.
Some of the cells obtained from patients or their relatives may be used to establish cell lines (a living tissue sample) that can be grown in the laboratory and used for experiments.
The purpose of this protocol is to collect protein, DNA, and RNA from blood, sputum, urine and/or tissue samples from patients with the diagnosis of Pentalogy of Cantrell (POC) or other related syndromes that could involve mutation of any of the genes encoding nonmuscle myosin heavy or light chains. In the case of patients with the diagnosis of POC, we will also be looking for any exomic/genomic mutations that could be associated with this syndrome. We have produced a mouse model with the mutant mice exhibiting problems with ventral wall closure including extrathoracic location of the heart (ectopia cordis), and defects in the abdominal wall with protrusion of the guts and liver. The mice have severe defects in both the heart and brain, and resemble humans born with POC, who manifest these same abnormalities.
