A novel deletion mutation in the LPA gene in a middle-aged woman with ischaemic stroke.

ABSTRACT:

Background

Genetic diversity of the human LPA gene locus is associated with high plasma concentrations of lipoprotein(a) [Lp(a)]. High Lp(a) concentrations are strongly associated with a high incidence rate of ischaemic stroke.

Case presentation

A 46-year-old female Chinese patient suffered from ischaemic stroke. Upon admission to the hospital, the patient was diagnosed with an elevated level of plasma Lp(a). The patient's clinical symptoms were alleviated by administration of basilar artery stent thrombectomy, mannitol, and aspirin. A novel compound heterozygous deletion of the region containing exons 3-16 covering kringle IV copy number variation (KIV CNV) domains in the LPA gene was observed in genetic analysis by next-generation sequencing and confirmed by qPCR.
