Description

A Chinese family with FV deficiency was included, and the patient and family members underwent mutation analysis. Then, patients from Keelung City (Taiwan) were screened for F5 polymorphism; the Chang Gung Human Database was used to determine single-nucleotide variants in the non-FV-deficient patient population.

Notes

Eight mutation sites on the F5 gene locus, including exon 16 homozygote Met1736Val and seven heterozygous mutations, including Asp68His, were found. Moreover, Met1736Val was found to be the dominant mutation in people living in Taiwan community, and this result was compared with the records of the Chang Gung Human Database. The abovementioned polymorphisms may result in a variable incidence of FV deficiency in Keelung City, thereby facilitating carrier diagnosis and prenatal diagnosis in most FV-deficient families.
