Later on, liver biopsy and splenic aspiration cytology was performed, which also showed same type of foamy cells. Type A is very rare and a severe infantile form with neurologic degeneration resulting in death usually by 3 years of age. [msjonline.org]
Symptomatic Management Gastrointestinal symptoms [2, 4]: (1) patients with dysphagia become malnourished and are at risk of silent aspiration, requiring a softening and thickening of food and antibiotics to avoid aspiration pneumonia. [hindawi.com]
This may result in the inhalation of foreign materials into the airways and lungs (aspiration pneumonia). [rarediseases.org]

Subsequent analysis of measures of axial and radial diffusivity suggest that these changes are contributed to by both impaired myelination and altered axonal structure. [neurology.org]
The identical biochemical patterns observed in NPC1 and NPC2 mutants suggest that the two NPC proteins function in a coordinate fashion in the cellular transport of cholesterol, glycolipids and other cargo. [medicinenet.com]
The incidence of NP-C is widely reported at 1 in 120,000, although recent evidence suggests this may be an under-estimate. [npuk.org]
