| T1 |
0-76 |
Sentence |
denotes |
Novel CRELD1 gene mutations in patients with atrioventricular septal defect. |
| T2 |
77-88 |
Sentence |
denotes |
BACKGROUND: |
| T3 |
89-262 |
Sentence |
denotes |
Atrioventricular septal defects (AVSDs) occur as clinical defects of several different syndromes, as autosomal dominant defects, and as sporadically occurring malformations. |
| T4 |
263-399 |
Sentence |
denotes |
Consequently, there is genetic heterogeneity, but until recently, little is known about the genes involving in the pathogenesis of AVSD. |
| T5 |
400-474 |
Sentence |
denotes |
CRELD1 gene, a novel cell adhesion molecule, is a candidate gene for AVSD. |
| T6 |
475-483 |
Sentence |
denotes |
METHODS: |
| T7 |
484-552 |
Sentence |
denotes |
This study included 133 patients with AVSD and 200 healthy controls. |
| T8 |
553-643 |
Sentence |
denotes |
Peripheral blood samples were collected and genomic DNA was extracted from the leukocytes. |
| T9 |
644-722 |
Sentence |
denotes |
CRELD1 was amplified by polymerase chain reaction (PCR) with specific primers. |
| T10 |
723-801 |
Sentence |
denotes |
The sequences of PCR products were compared between the patients and controls. |
| T11 |
802-810 |
Sentence |
denotes |
RESULTS: |
| T12 |
811-1001 |
Sentence |
denotes |
In a patient, a C-to-G transition was identified at nucleotide 857 in exon 8 that resulted in a substitution of alanine for proline at amino acid 286 in the first calcium-binding EGF domain. |
| T13 |
1002-1091 |
Sentence |
denotes |
This patient had an isolated partial AVSD and the mutation was inherited from her mother. |
| T14 |
1092-1185 |
Sentence |
denotes |
Another mutation was detected in a patient with a partial AVSD and evidence of Down syndrome. |
| T15 |
1186-1355 |
Sentence |
denotes |
The heterozygous c.973G>A transition in exon 9 resulted in a substitution of lysine for glutamic acid at amino acid 325 (E325K) in the second calcium-binding EGF domain. |
| T16 |
1356-1368 |
Sentence |
denotes |
CONCLUSIONS: |
| T17 |
1369-1468 |
Sentence |
denotes |
Two novel CRELD1 mutations were identified in the calcium-binding EGF domain in patients with AVSD. |
| T18 |
1469-1638 |
Sentence |
denotes |
CRELD1 is likely to be an AVSD-susceptibility gene and CRELD1 mutations may increase the risk of developing a heart defect rather than being a direct causative mutation. |
