Simplle families include individuals with a history of “blistering” but are unaware that these individuals have EBS. The diagnosis of epidermolysis bullosa simplex EBS is established in a proband by the identification of biallelic pathogenic variants in EXPH5 or TGM5 or heterozygous or rarely biallelic pathogenic variants in KRT5 or KRT14 by molecular genetic testing ; examination of a skin biopsy using immunofluorescence microscopy and transmission electron microscopy may be considered ampolloaa can have limitations in the diagnosis of EBS.

In most cases, the associated phenotypes i. This was a descriptive, cross-sectional chart-review study in which we recorded the type and main subtypes of EB and the presence or absence of DC. Genetic basis of Bart’s syndrome: Autosomal recessive pathogenic variants in TGM5 are often missense variants that affect the crosslinking capabilities of the enzyme.

The molecular genetics of the genodermatoses: Pathogenic missense variants give rise to abnormal gene products that may not assemble correctly into functional keratin intermediate filaments. Death within the first days after birth secondary to profound fluid and electrolyte imbalance is common.

The area where the layers meet is called the basement epidermolisie. EXPH5 encodes a RAB27b GTPase e;idermolisis protein, exophilin-5, which is not a structural protein, but rather plays a role in cell membrane trafficking and vesicle formation. The most recent classification system, referred to as the “onion skin” terminology, arose from the most recent international consensus meeting, the recommendations of which were published in June [ Fine et al ].
