Juvenile hyaline fibromatosis

Juvenile hyaline fibromatosis
Autosomal recessive pattern is the inheritance manner of this condition

Juvenile hyaline fibromatosis (also known as "Fibromatosis hyalinica multiplex juvenilis,"[1] "Murray–Puretic–Drescher syndrome"[1]) is a very rare, autosomal recessive disease due to mutations in capillary morphogenesis protein-2 (CMG-2 gene). It occurs from early childhood to adulthood, and presents as slow-growing, pearly white or skin-colored dermal or subcutaneous papules or nodules on the face, scalp, and back, which may be confused clinically with neurofibromatosis.[2]

Genetics

This condition is due to mutations in the anthrax toxin receptor-2 (ANTXR2) gene. This gene is also known as capillary morphogenesis protein-2.

This gene is located on the long arm of chromosome 4 (4q21.21).

Epidemiology

84 cases have been reported as of 2018.[3]

Clinical features

This condition is characterised by abnormal growth of hyalinized fibrous tissue with cutaneous, mucosal, osteoarticular and systemic involvement.

Clinical features include extreme pain at minimal handling in a newborn, gingival hypertrophy, subcutaneous nodules, painful joint stiffness and contractures, muscle weakness and hypotonia.

Prognosis

This is very poor with a median age at death of 15 months.

Management

There is no presently known curative treatment for this condition.

Management is supportive
