Abstract:
Objective:To analyze and clarify the clinical and pathogenic gene variation and genetic etiology of polycystic liver disease.Methods:The proband clinical data and family history were collected. Whole-exome sequencing technology was used to detect the proband gene variations. Fluorescence quantitative PCR validation was performed on the proband and his family to screen out pathogenic gene variation.Results:A multiple liver cyst was found in an 18-year-old male proband during a physical examination. There were no abnormalities in his liver function, and both his father and grandfather had multiple liver cysts without any obvious discomfort or other special manifestations. Whole exome sequencing suggested a heterozygous deletion in exon 1 (Exon 1) of the SEC63 gene in the proband. Real-time fluorescence quantitative PCR confirmed that the heterozygous deletion variation of the SEC63 gene Exon 1 of the proband came from his father, and the same heterozygous deletion was detected in his grandfather. The gene variant had a pathogenic variation that had been rarely reported before and was in accordance with the the American college of Medical Genetics and Genomics (ACMG) guidelines.Conclusions:The genetic etiology of this autosomal dominant polycystic liver disease has been clarified, and the heterozygous deletion of Exon1 of the SEC63 gene is a newly discovered gene variation that broadens the variation spectrum of the SEC63 gene.
