More Details: Objective To analyze the clinical and molecular genetic features in one pedigree with nail-patella syndrome(NPS), and provide evidence for genetic counseling and reproductive guidance for this family. Methods Whole-exon sequencing (WES)was performed to detect the gene variant of the proband and the whole family. Candidate variants were verified by Sanger sequencing and bioinformatic analysis. Using the key words of “nail-patella syndrome”and “prenatal diagnosis/antenatal diagnosis” as the searching words in both Chinese and English,relevant literatures were searched from PubMed, SinoMed, CNKI, Wanfang Data and Chongqing VIP databases up to December, 2022. Clinical data of NPS cases were collected and analyzed. Results The proband and aborted fetus carried a heterozygous variant c.736C>T (p.Arg246*) of the LMX1B. The same heterozygous variant was found in father rather than in mother. This variant has been proven to be pathogenic. Bioinformatic analysis predicted that the 246th amino acid was highly conserved among different species and p.Arg246* variant altered the structure and function of LMX1B protein. According to literature review, six cases of NPS confirmed by prenatal diagnosis were searched. All cases were diagnosed by ultrasound and/or molecular genetic analysis. Conclusion The heterozygous variant c.736C>T (p.Arg246*) of LMX1B gene is the pathogenic mutation in this NPS pedigree.
