Abstract

We here report on a 20-year-old female patient with EDS due to a homozygous CHST14 single nucleotide deletion resulting in D4ST-1 deficiency, accompanied by muscle hypoplasia and muscle weakness. Findings of muscle ultrasound, electromyography, and muscle biopsy pointed to a myopathy, similarly as in other EDS types. This myopathy probably contributes to the gross motor developmental delay in this type of EDS. © 2012 Wiley Periodicals, Inc.
