FKBP14 kyphoscoliotic Ehlers-Danlos Syndrome in adolescent patient: the first Colombian report

Ehlers-Danlos syndrome (EDS) is a group of clinically and genetically heterogeneous inherited connective tissue disorders, characterized by skin hyperextensibility, poor wound healing, joint hypermobility and tissue friability. Since 1997 a new spectrum of novel rare EDS-variants has been described, among which is included the EDS kyphoscoliotic type, characterized by severe muscular hypotonia at birth, severe progressive kyphoscoliosis, osteopenia, fragile eyeballs and vascular fragility. This EDS variant is caused by mutations in the PLOD1 gene; however, a rare recessive variant that compromises the FKBP14 gene has been reported, with additional clinical findings that includes gross motor developmental delay, myopathy, hearing impairment and a normal ratio of lysyl pyridinoline to hydroxylysyl pyridinoline in urine. We report the first Colombian patient with a FKBP14 c.362dupC mutation, with clinical features that include generalized hypotonia, delayed gross motor milestones, hearing loss, early-onset progressive kyphoscoliosis, joint hypermobility and foot deformities.
