Three novel missense variants in two families with JAG2-associated limb-girdle muscular dystrophy.

Limb-girdle muscular dystrophy recessive 27 is associated with biallelic variants in JAG2, encoding the JAG2 notch ligand. Twenty-four affected individuals from multiple families have been described in two reports. We present two Australian families with three novel JAG2 missense variants: (c.
