CF databases:	c.1040G>C , p.Arg347Pro D , CF-causing ; CFTR1: This mutation destroys a Hha I restriciton site and creates an NcoI site and occurred in a family diagnosed as PS. The mutation have been identified and analyzed using the SSCP technique. c.1040G>A , p.Arg347His D , CF-causing ; CFTR1: The patient is of Italian origin and carries the [delta]F508 mutation on the other chromosome. Initially we thought this was the same mutation as R347 because it destroys the same hhai site; however, R347H does not create the NcoI site. c.1040G>T , p.Arg347Leu (CFTR1) D , A nucleotide change, G->T at position 1172, was detected leading to R347L. The other chromosome carries a [delta]F508. This mutation was found on one chromosome among 150 CF chromosomes screened. c.1039C>T , p.Arg347Cys (CFTR1) ? , This mutation was identified by DGGE and direct sequencing.

Analysis of exocrine pancreatic function in cystic fibrosis: one mild CFTR mutation does not exclude pancreatic insufficiency.
Eur J Clin Invest. 2001 Sep;31(9):796-801., [PMID:11589722]

Abstract [show]
BACKGROUND: Cystic fibrosis (CF) is the most common cause of exocrine pancreatic insufficiency in childhood. The aim of the present study is to evaluate the correlation between genotype and exocrine pancreatic insufficiency in CF patients. The special emphasis was put on the analysis of mild CFTR mutations. DESIGN: The study comprised 394 CF patients and 105 healthy subjects (HS). Elastase-1 concentrations were measured in all subjects. RESULTS: Severe pancreatic insufficiency was associated with the presence of two CFTR gene mutations (DeltaF508, N1303K, CFTR dele 2,3 (21kb), G542X, 1717-1G-A, R533X, W1282X, 621GT, 2183AAG, R560T, 2184insA and DeltaI507, G551D, 895T) and mild insufficiency with the presence of at least one mutation (R117H, 3171insC, A155P2, 138insL, 296 + 1G-A, E92GK, E217G, 2789 + 5G-A. 3849 + 1kbC-T/3849 + 1kbC-T) genotype resulted in high elastase-1-values. However, in case of patients with genotype DeltaF508/3849 + 10kbC-T, 1717-1GA/3849 + 10kbC-T as well as with DeltaF508/R334W, both high and low elastase-1 concentrations were found. Low E1 values were found in a patient with DeltaF508/R347P genotype. CONCLUSION: Patients who carry two 'severe' mutations develop pancreatic insufficiency, whereas those who carry at least one 'mild' usually remain pancreatic sufficient. However, the presence of one mild mutation does not exclude pancreatic insufficiency.

85 Previously, it has been shown that pancreatic insufficiency was related to mutation G551D and pancreatic sufficiency to R347W and S549N [11]. Login to comment
