The walk was organised by an NGO, Lysosomal Storage Disorders Support Society, India (LSDSS) on the eve of International Gaucher Day.
Nearly 30 patients afflicted by LSDs and their caregivers marched from Jantar Mantar to Connaught Place holding placards and banners to highlight their plight.
LSDs are a group of rare inherited metabolic disorders that result from defects in lysosomal function. Lysosomes are sacs of enzymes within cells that digest large molecules and pass the fragments on to other parts of the cell for recycling.
The NGO claimed that "two committees have been formed this year to address the concerns of patients with rare diseases including, LSDs, but nothing concrete has emerged in terms of providing free treatment, the primary demand of these patients and families."

An awareness programme held after the walk saw discussion on the ways and means of funding the treatment of rare genetic disorders like Gaucher, MPS (mucopolysaccharidoses), Fabry and Pompe.
Gaucher's disease is a genetic disorder in which glucocerebroside accumulates in cells and certain organs.
"Enzyme Replacement Therapy (ERT), the most effective treatment for LSDs has been available in India however most patients are deprived from receiving the treatment due to their high cost. These treatments are not supported by government or insurance companies unlike in developed countries," the NGO said.
"ERT is critical to improve the quality of life for patients suffering with rare genetic disorders such as Gaucher disease for which there is no cure. Without treatment, there is progressive accumulation of partially degraded compounds which stealthily leads to multi-organ dysfunction," said Dr A P Dubey, Head of Department of Pediatrics at Maulana Azad Medical College.
