Popis: Kindler syndrome is a rare genodermatosis. Major clinical criteria include acral blistering in infancy and childhood, progressive poikiloderma, skin atrophy, abnormal photosensitivity, and gingival fragility.FERMT1 gene was sequenced in 5 patients with a clinical diagnosis of Kindler syndrome.We report a novel pathogenic variant detected in four unrelated families of Paraguayan origin, where one nucleotide deletion in FERMT1 gene (c.450delG) is predicted to cause a frameshift mutation leading to loss of function. Haplotype analysis revealed the propagation of an ancestral allele through this population.The identification of this recurrent pathogenic variant enables optimization of molecular detection strategies in our patients, reducing the cost of diagnosis.
