Clinical Description OMIM For a general phenotypic description and a discussion of genetic heterogeneity of neuronal ceroid lipofuscinosis (NCL; CLN), see CLN1 (256730).

Various forms of CLN are characterized by developmental regression, visual loss, and epilepsy in addition to ...
Genotype-Phenotype Correlations OMIM In a Pakistani infant with severe congenital NCL, Siintola et al. (2006) identified a homozygous null mutation in the CTSD gene (116840.0003). The extreme clinical phenotype, including postnatal apnea, seizures, and early death, were consistent with complete inactivation ...
Molecular genetics OMIM In a patient with cathepsin D deficiency manifesting as a CLN-like disorder, Steinfeld et al. (2006) identified compound heterozygosity for missense mutations in the CTSD gene. The maternal allele carried a phe229-to-ile substitution (F229I; 116840.0001), and the paternal ...
