MYH7B and heart disorder: Conversely, 23 significantly contracted genes were mainly relevant to biological processes such as fatty acid degradation (ALDH3A2) (GO:0001561), myocardium development (GO:0048739), muscle contraction and cardiac disease (MYH6, MYH7, and MYH7b), olfactory receptor activity (OR52B2, OR52K1, and OR4S1) (GO:0004984), and the pathways of olfactory transduction, metabolism, and cardiac muscle contraction (Supplementary Table S16).
