From the abstract
Biallelic ITGA3 variants cause a rare subtype of junctional epidermolysis bullosa named interstitial lung disease, nephrotic syndrome, and epidermolysis bullosa. Interstitial lung disease, nephrotic syndrome, and epidermolysis bullosa is characterized by extensive clinical heterogeneity, suggesting the existence of modifier genes.
