Niemann-Pick
by Yael Rosenberg, RN
Description
Niemann-Pick is an autosomal recessive genetic disease.
There are four clinical types of Niemann-Pick Disease: A, B, C, D.
Type A and Type B are caused by the lack of a substance called ASM-acid
sphingomylinase which breaks down a substance called sphingomyeline.
Lack of ASM causes buildup of sphingomyeline in certain cells and
causes damage to the central nervous system, liver, and lungs. Type
A and B are the result of mutation of the SMPD1 gene located on
chromosome 11.
Though both Type A and B are caused by deficiency of ASM, Type A,
which is most prevalent, is a severe neurological disease that
generally leads to death between two and three years of age. Type B
has little or no neurological involvement and many survive into late
childhood or adulthood.
Type C and D are also caused by excess deposition of sphingomyelin,
as patients do not properly transport sphingomyelin and that too
results in its accumulation of sphingomyeline. This is the result of
mutations in the NPC1 gene on chromosome 18 and NPC2 gene on
chromosome 14.
However, it is Niemann-Pick Disease A and B types that have a higher
incidence in Ashkenazi Jews, compared to the general population.
Symptoms
Symptoms of Neimann-Pick Type A
Symptoms of Neimann-Pick Type B
Symptoms of Neimann-Pick Type A
Symptoms and signs of Type A include: (vary from person to
person)
Failure to thrive (gain weight or grow at expected rate)
Progressive deterioration of nervous system
Coordination and motor-skill difficulties that progressively
worsen
Progressive spasticity
Abdominal distention within 3-6 months
Enlarged liver, and\or spleen
May also present with jaundice in infancy and progressive liver
failure
Feeding difficulties
Blindness
A cherry red spot in the eye, visible by special eye exam.
Symptoms of Niemann-Pick Type B
Neimann-Pick Type B is less severe and there is practically no
neurological involvement. However, it does cause liver, spleen,
lymph node, and bone marrow problems. Notable symptoms are abdominal
distention and respiratory difficulties including repeated lung
infections.
Incidence and Carriers
Disease Frequency: 1 in 40,000 for type A in the Jewish population
1 in 250,000 for both types A & B in the general population
Carrier Frequency: One in 80 Ashkenazi Jews is a Type A carrier.
Unknown for type B
though it is estimated to not be greater than any other race
Treatment
Currently there is no effective cure or treatment for type A, so
therapy is basically supportive.
Some encouraging results have been seen with bone marrow
transplantation for Type B Niemann Pick Disease.
Mount Sinai Hospital in New York in conjunction with Genzyme
Corporation is working on new treatment modes for Type B Niemann-Pick
Disease. They will be focusing on Enzyme Replacement Therapy and
Gene Therapy.
Testing
Diagnosis is achieved by testing blood, and measuring the ASM
activity in the white blood cells. This test is effective in
identifying persons with Niemann-PIck Type A and B disease, However
it has been found unreliable in detecting persons who are carriers
of Niemann-Pick
Carrier screening test blood test to determine presence of SMPD1
gene mutation in Nieman-Pick Type A &B
Prenatal diagnosis for Niemann-Pick utilizing CVS (Chorionic Villus
Sampling) or Amniocentesis
