INTRODUCTION.
Hypobeta Lipoproteinemia is a disorder consisting of low levels of LDL cholesterol or apolipoprotein-B below the 5th-percentile. The patient can have hypobetalipoproteinemia and simultaneously have high levels of HDL cholesterol.
There is evidence familial hypobetalipoproteinemia-1 is caused by mutation in the APOB gene on cytogenetic location 2p24.1 and genomic coordinates 2:21,001,429-21,044,073 . The screenshot of the APOB gene 42,645 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides APOB in the 2p24.1 cytogenetic location are listed BENEATH.
