Objective:
To examine transforming growth factor beta 1 (TGFβ1) gene polymorphisms in Turkish patients with nonsyndromic cleft lip with/without cleft palate (nsCL/P).
Methods:
A total of 205 Turkish subjects were included; 80 nsCL/P patients and 125 unrelated control individuals. Analysis of gene polymorphisms was carried out by polymerase chain reaction and DNA sequencing.
Results:
We found the substitution of a proline by a leucine at codon 10 (Pro10Leu) and the substitution of an arginine by a proline at codon 25 (Arg25Pro) in exon 1 of the TGFβ1 gene in nsCL/P patients.
Conclusion:
This is the first report investigating prevalence of TGFβ1 polymorphisms in Turkish patients with nsCL/P.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
