Order Niemann-Pick Disease Test | Carrier TestingNiemann-Pick disease is a group of inherited lysosomal storage disorders in which fatty substances accumulate in cells, leading to progressive damage in organs such as the liver, spleen, lungs, and brain. Carrier testing examines a small number of well-characterized mutations in the relevant gene to determine whether a person carries a change that could be passed to a child.
About Niemann-Pick Disease Test | Carrier Testing in Longview
Niemann-Pick disease Type A and Type B arise from deficient activity of acid sphingomyelinase, an enzyme encoded by the SMPD1 gene.
The enzyme acid sphingomyelinase normally breaks down sphingomyelin, a lipid found in cell membranes. When the enzyme is deficient, sphingomyelin accumulates within lysosomes and disrupts normal cellular function. Type A is a severe, early-onset form with rapid neurologic decline, while Type B is generally later in onset and primarily affects the liver, spleen, and lungs.
Niemann-Pick disease is inherited in an autosomal recessive pattern. A person who carries one altered copy of the SMPD1 gene typically has no symptoms, because one functional copy is sufficient to produce adequate enzyme activity. Two carriers have a one-in-four chance with each pregnancy of having an affected child.
Carrier testing identifies specific mutations that are more common in certain populations, so a negative result reduces but does not eliminate the possibility of being a carrier. Genetic counseling is recommended to interpret results in the context of family history and to discuss reproductive options.
