A Report of a Novel Pathogenic Variant in a Family with Buschke–Ollendorf Syndrome

Abstract

Buschke–Ollendorf Syndrome (BOS) is a benign autosomal dominant disorder caused by pathogenic mutations in LEMD3. Here, we describe a family diagnosed to have varied phenotypes associated with BOS. Single gene testing of LEMD3 detected a heterozygous frameshift pathogenic variant in both the affected family members. Besides the phenotypic description, this report highlights the need for a comprehensive evaluation in connective tissue disorders and the importance of genotype–phenotype correlation in BOS.
