P-125: Identification of Novel Missense Mutations of The TGFBR3 Gene in Chinese Women with Premature Ovarian Failure

The aim of this study was to assess the ssociation between human transforming growth factor b receptor,type III (TGFBR3) and idiopathic premature ovarian failure (POF) in a Chinese population.
Materials and methods
A total of 112 Chinese women with idiopathic POF and 110 normal controls were examined. DNA samples prepared from blood leukocytes were used as templates for polymerase-chain reaction amplification of DNA fragments from TGFBR3. The gene fragments were sequenced. Web-based programs, including PolyPhen, Sorting Intolerant from Tolerant (SIFT), Prediction of Pathological Mutations (PMUT), ScanProsite and ClustalW2, were used to predict the potential functional and structural impacts of the missense variants of TGFBR3.
A total of 11 novel variants were identified. Among them, six were found only in the POF patients. Two missense variants, p.E459G and p.P825L, which are conserved in primates, were predicted to have functional and structural impacts on the TGFBR3 protein.
The other four variants (c.381+12A>C, c.2431 7A>G, p.S172S and p.C220C) were considered benign. However, further functional studies are necessary to confirm these findings.
