An important gene associated with Hartsfield Syndrome is FGFR1 (Fibroblast Growth Factor Receptor 1), and among its related pathways/superpathways are Downstream signaling of activated FGFR2 and Signaling by Receptor Tyrosine Kinases. Affiliated tissues include brain and pituitary, and related phenotypes are ptosis and respiratory insufficiency
