The c.863A>G (p.Glu288Gly) variant of the CTSD gene is not associated with CLN10 disease.

ABSTRACT:

Background

Cathepsin D is a lysosomal aspartic protease encoded by the CTSD gene. It plays important roles in many biological processes. Biallelic loss-of-function mutation of CTSD is considered a cause of CLN10 disease. CLN10 is a rare autosomal recessive disorder that is one of 14 types of neuronal ceroid lipofuscinoses (NCLs). To date, only a few cases of CLN10 and 12 disease-causing mutations have been reported worldwide.

Methods

Exome sequencing was performed on a 15-year-old girl with pervasive brain developmental disorder. The effects of the identified variants were investigated through multiple functional experiments.

Results

There were no differences in mRNA and protein expression, intracellular localization, maturation, and proteolytic activity between the c
