Arina Puzriakova (Genomics England Curator)

Comment on list classification: No human cases with pathogenic DLX2 variants reported to date and therefore this gene should be rated Red.

Mice lacking DLX1 and DLX2 had slower small bowel transit and reduced or absent neurally-mediated contraction complexes, and have reduced vasoactive intestinal peptide (VIP) expression and fewer VIP-lineage neurons in their enteric nervous system. Small bowel motility seemed normal in adult mice lacking only DLX1 (PMID: 32017713).
