abstract = {Hirschsprung disease (HSCR, OMIM 142623) involves
congenital intestinal obstruction caused by dysfunction of
neural crest cells and their progeny during enteric nervous
system (ENS) development. HSCR is a multifactorial disorder;
pathogenetic variants accounting for disease phenotype are
identified only in a minority of cases, and the
identification of novel disease-relevant genes remains
challenging. In order to identify and to validate a
potential disease-causing relevance of novel HSCR candidate
genes, we established a complementary study approach,
combining whole exome sequencing (WES) with transcriptome
analysis of murine embryonic ENS-related tissues, literature
and database searches, in silico network analyses, and
functional readouts using candidate gene-specific
genome-edited cell clones. WES datasets of two patients with
HSCR and their non-affected parents were analysed, and four
novel HSCR candidate genes could be identified: ATP7A,
SREBF1, ABCD1 and PIAS2. Further rare variants in these
genes were identified in additional HSCR patients,
suggesting disease relevance. Transcriptomics revealed that
these genes are expressed in embryonic and fetal
gastrointestinal tissues. Knockout of these genes in
neuronal cells demonstrated impaired cell differentiation,
proliferation and/or survival. Our approach identified and
validated candidate HSCR genes and provided further insight
into the underlying pathomechanisms of HSCR.},
