Sentence |
denotes |
Identification of a novel FBN1 gene mutation in a Chinese family with Marfan syndrome. |
| T2 |
87-95 |
Sentence |
denotes |
PURPOSE: |
| T3 |
96-199 |
Sentence |
denotes |
To identify the mutation in the fibrillin-1 gene (FBN1) in a Chinese family with Marfan syndrome (MFS). |
| T4 |
200-208 |
Sentence |
denotes |
METHODS: |
| T5 |
209-311 |
Sentence |
denotes |
Patients and family members were given complete physical, ophthalmic, and cardiovascular examinations. |
| T6 |
312-439 |
Sentence |
denotes |
Genomic DNA was extracted from leukocytes of venous blood of six individuals in the family and 170 healthy Chinese individuals. |
| T7 |
440-607 |
Sentence |
denotes |
All of the 65 coding exons and their flanking intronic boundaries of FBN1 were amplified in the proband by polymerase chain reaction and followed by direct sequencing. |
| T8 |
608-749 |
Sentence |
denotes |
The mutation identified in the proband was screened in the other family members and the 170 healthy Chinese individuals by direct sequencing. |
| T9 |
750-839 |
Sentence |
denotes |
Protein conservation analysis was performed in six species using an online ClustalW tool. |
| T10 |
840-987 |
Sentence |
denotes |
Protein structure was modeled based on the Protein data bank and mutated in DeepView v4.0.1 to predict the functional consequences of the mutation. |
| T11 |
988-996 |
Sentence |
denotes |
RESULTS: |
| T12 |
997-1164 |
Sentence |
denotes |
A novel heterozygous c.3703T>C change in exon 29 of FBN1 was detected in the proband, which resulted in the substitution of serine by proline at codon 1235 (p.S1235P). |
| T13 |
1165-1309 |
Sentence |
denotes |
This mutation was also present in two family members but absent in the other, unaffected family members and the 170 healthy Chinese individuals. |
| T14 |
1310-1503 |
Sentence |
denotes |
The mutant residue located in the calcium binding epidermal growth factor-like#15 domain is highly conserved among mammalian species and could probably induce conformation change of the domain. |
| T15 |
1504-1516 |
Sentence |
denotes |
CONCLUSIONS: |
| T16 |
1517-1622 |
Sentence |
denotes |
We indentified a novel p.S1235P mutation in FBN1, which is the causative mutation for MFS in this family. |
| T17 |
1623-1750 |
Sentence |
denotes |
Our result expands the mutation spectrum of FBN1 and contributes to the study of the molecular pathogenesis of Marfan syndrome. |
