Multiple genes with high loading in LF1 relate to muscular dystrophy with the Dmd gene ranking in top 100 genes, and all 3 Col6a genes (Col6a1, Col6a2 and Col6a3 genes) responsible for Ulrich muscular dystrophy are present in the top 40 genes in LF1 (S5 Fig). This evidence concerns the gene COL6A1 and muscular dystrophy.
