0-119 |
Sentence |
denotes |
Four novel mutations in the thiazide-sensitive Na-Cl co-transporter gene in Japanese patients with Gitelman's syndrome. |
| T2 |
120-131 |
Sentence |
denotes |
BACKGROUND: |
| T3 |
132-289 |
Sentence |
denotes |
Gitelman's syndrome (GS) is an autosomal recessive disorder resulting from inactivating mutations in the thiazide-sensitive Na-Cl co-transporter (NCCT) gene. |
| T4 |
290-340 |
Sentence |
denotes |
To date, almost 90 mutations have been identified. |
| T5 |
341-418 |
Sentence |
denotes |
It is possible that there is a population-specific distribution of mutations. |
| T6 |
419-508 |
Sentence |
denotes |
In this study, we analysed mutations in the NCCT gene of seven Japanese patients with GS. |
| T7 |
509-517 |
Sentence |
denotes |
METHODS: |
| T8 |
518-640 |
Sentence |
denotes |
Peripheral blood mononuclear cells were isolated from patients with GS, their family members and healthy control subjects. |
| T9 |
641-786 |
Sentence |
denotes |
A mutation analysis of the NCCT gene was performed completely by direct automated sequencing of polymerase chain reaction-amplified DNA products. |
| T10 |
787-876 |
Sentence |
denotes |
In patients with a deletion or splice site mutation, we undertook cDNA sequence analysis. |
| T11 |
877-885 |
Sentence |
denotes |
RESULTS: |
| T12 |
886-915 |
Sentence |
denotes |
We identified nine mutations. |
| T13 |
916-1124 |
Sentence |
denotes |
Five of them [c.185C>T (Thr60Met), c.1712C>T (Ala569Val), c.1930C>T (Arg642Cys), c.2552T>A (Leu849His) and c.1932delC] have been reported in Japanese patients, but not in GS patients from other ethnic groups. |
| T14 |
1125-1238 |
Sentence |
denotes |
The remaining four mutations [c.7A>T (Met1Leu), c.1181_1186+20del26, c.1811_1812delAT and IVS16+1G>A] were novel. |
| T15 |
1239-1372 |
Sentence |
denotes |
In cDNA derived from a patient with c.1181_1186+20del26, a deletion of exon 9 and a frameshift at the start of exon 10 were observed. |
| T16 |
1373-1487 |
Sentence |
denotes |
In cDNA derived from patients with IVS16+1G>A, an additional 96 bp insertion between exons 16 and 17 was observed. |
| T17 |
1488-1604 |
Sentence |
denotes |
Six out of seven patients were compound heterozygotes, and the remaining one carried a single heterozygous mutation. |
| T18 |
1605-1617 |
Sentence |
denotes |
CONCLUSIONS: |
| T19 |
1618-1700 |
Sentence |
denotes |
We found four novel mutations in the NCCT gene in seven Japanese patients with GS. |
| T20 |
1701-1857 |
Sentence |
denotes |
Moreover, our study suggests that the distribution of mutations in the NCCT gene in Japanese GS patients potentially differs from that in other populations. |
