A heterozygous mutation in ITGB4 causing a mild phenotype of junctional epidermolysis bullosa
PEDIATRIC DERMATOLOGY(2023)
摘要
Mutations in ITGB4 are known to cause autosomal recessive junctional epidermolysis bullosa (JEB), which is manifested by severe blistering and granulation tissue, usually complicating pyloric atresia and even leading to death. ITGB4-associated autosomal dominant epidermolysis bullosa has rarely been documented. Herein, we identified a heterozygous pathogenic variant (c.433G>T; p.Asp145Tyr) in ITGB4 causing a mild phenotype of JEB in a Chinese family.
