ABSTRACT
OBJECTIVE@#To carried out prenatal diagnosis and genetic analysis for a case with Nail-patella syndrome.@*METHODS@#Based on the clinical phenotype and prenatal imaging, genetic testing and prenatal diagnosis were carried out through whole exome sequencing (WES) and Sanger sequencing.@*RESULTS@#Analysis of amniotic fluid showed that the fetus has carried a heterozygous c.139+1G>T splicing site variant [Chr9(GRCh37) g.129376868G>T] of the LMX1B gene, which was verified by Sanger sequencing. The same heterozygous variant was found in the pregnant woman, her daughter and her mother but not in her husband. Searching of HGMD database showed that the c.139+1G>T was previously unreported.@*CONCLUSION@#Nail-patella syndrome is an autosomal dominant genetic disorder with various clinical manifestations. WES is helpful for its genetic and prenatal diagnosis.
