Magnetic resonance imaging shows muscle atrophy and fatty infiltration of the muscles. Muscle biopsy shows fibrosis and fatty infiltration. Skin biopsy shows fibrosis and alterations of the elastic network.

Genetics

This condition is caused by mutations in the (FAM111B) gene. This gene is located on the long arm of chromosome 11 (11q12.1).

The inheritance of this condition is autosomal dominant.

Diagnosis

This diagnosis is made by sequencing the FAM111B gene.

Differential diagnosis Poikiloderma of Weary

Management

There is presently no curative treatment. Management is supportive.

Epidemiology

The prevalence is not known but this is considered to be a rare disease. About fifty cases have been described in the literature up to 2019.

History

This condition was first described in 2006.Khumalo NP, Pillay K, Beighton P, Wainwright H, Walker B, Saxe N, Mayosi BM, Bateman ED (2006) Poikiloderma, tendon contracture and pulmonary fibrosis: a new autosomal dominant syndrome? Br J Dermatol 155(5):1057-1061
