In addition to the LMNA mutation c.736C>T (p.Gln246Stop), only two variants co-segregated with the fibromatosis phenotype: a novel missense variant in the Asteroid Homolog 1 gene (ASTE1 NM_001288950: c.230T>C, p.Val77Ala) and a rare known missense variant in the Olfactory Receptor Family 51 Subfamily A Member 7 gene OR51A7 NM_001004749: c.763A>G, p.Ile255Val). This evidence concerns the gene LMNA and fibromatosis.
