This designation builds on our clinical portfolio of AAV gene therapies that have received FDA and EMA orphan drug designations, which is an important validation of the scientific and clinical translation of these products for the severely underserved CLN1 patient population, stated Timothy J.
About Infantile Batten Disease: Infantile neuronal ceroid lipofuscinosis (INCL) is a severe lysosomal disease caused by mutations in the CLN1 gene, which encodes the soluble lysosomal enzyme Palmitoyl-Protein-Thioesterase-1 (PPT1) and result in osmiophilic granules accumulating in lysosomes and leading to neuroinflammation, neurodegeneration and death.
DBS were obtained from 6 patients with CLN1, 5 patients with CLN2, and 2 patients with the juvenile form CLN3, as well as from 70 control individuals.
In the infantile and late infantile subtypes of NCL, the disorder is brought on by inherited mutations in the CLN1 gene, which codes for palmitoyl-protein thioesterase 1 (PPT1) or in the CLN2 gene, which codes for tripeptidyl peptidase I (TPP-I), respectively.
In two subtypes of NCL, infantile and late infantile, the disorder is brought on by inherited mutations in the CLN1 gene, which codes for palmitoyl-protein thioesterase 1 (PPT1) or in the CLN2 gene, which codes for tripeptidyl peptidase I (TPP-I).
In two subtypes of the NCLs, infantile and late infantile NCL, the disorders are brought on by inherited genetic mutations in the CLN1 gene, which codes for palmitoyl-protein thioesterase 1 (PPT1) and in the CLN2 gene, which codes for tripeptidyl peptidase I (TPP-I).
In two sub-types of the NCLs - infantile and late infantile or, more technically, CLN1 and CLN2 - normally secreted housekeeping lysosomal enzymes are either defective or missing altogether, as a result of gene mutations.
