The most crucial features are hepatosplenomegaly and elevated liver enzymes. This study aims to identify genetic variants causing the disease in three Iranian families with congenital liver disease using molecular techniques.</span></span></span></span></span></span></span></span></span></span><br> <br> <span style="font-size:10pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="line-height:normal"><span style="tab-stops:396.55pt"><span style="font-family:Calibri,sans-serif"><b><i><span lang="EN-GB" style="font-size:12.0pt"><span new="" roman="" style="font-family:" times=""><span style="color:black"><span style="letter-spacing:-.3pt">Methods:</span></span></span></span></i></b> <span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times=""><span style="color:black"><span style="letter-spacing:-.3pt">Patients were referred to Next Generation Genetic Polyclinic (NGGC) in Mashhad after confirmed congenital liver disease diagnosis by gastroenterologists. Following informed consent signed by participants, DNA was extracted from blood samples. Whole exome sequencing (WES) was performed for three probands.
