Primary Outcome Measures:
  • Time to Death [ Time Frame: Up to two years. ]

Enrollment: 40
Study Start Date: November 2010
Study Completion Date: March 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Detailed Description:
The objective of this study is to characterize key aspects of the clinical course of LAL deficiency/Wolman phenotype in patients including, but not limited to, survival and growth parameters, to serve as a historical control to inform the evaluation and care of affected patients and to provide a reference for efficacy studies of enzyme replacement or other novel therapies.

Ages Eligible for Study:   Child, Adult, Senior

Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Deceased patients diagnosed with LAL deficiency/Wolman phenotype in 1985 or later.

Inclusion Criteria:

  • Deceased patients diagnosed with LAL deficiency/Wolman phenotype in 1985 or later provided they have required data points in their medical records.

Exclusion Criteria:

  • Patients will be excluded from the study if the required data points for inclusion are not available.
  • Living LAL deficiency/Wolman phenotype patients will be excluded
