Cardiac disease as the presenting feature of mucopolysaccharidosis type IIIA: A case report.


ABSTRACT: Severe cardiac involvement is a common feature of mucopolysaccharidoses (MPS), but occurs only rarely in MPS III (Sanfilippo syndrome). We report herein a case of MPS III-A having cardiac involvement as its first manifestation. Analysis of the SGSH gene showed homozygosity for the novel mutation p.G80V. We propose that MPS disorders, including MPS III-A, should be included in the differential diagnosis of every case of cardiomyopathy presenting during the first year of life.
