ABSTRACT
Abstract Introduction:
Neuronal ceroid lipofuscinosis (NCLs) is an autosomal recessive neurodegenerative disorders group. We report the first case in Colombia involving a new genetically confirmed variant of a homozygous CLN6 mutation. Case report 12-year-old male, history of blood parents and average growth until 5 years of age. At this age began focal crises, progressive regression of neurodevelopment, severe cognitive deficit, and swallowing disorder that led to gastrostomy. Clinical exome + CNVs + mitochondrial DNA genetic study identified variant NM_017882.3 (CLN6) c. 22C>T, p. (Gln8*) in homozygous, deleterious. Late-onset infantile neuronal ceroid lipofuscinosis was diagnosed.Discussion:
Mutations in the CLN6 gene are associated with late-onset infantile lipofuscinosis of autosomal recessive inheritance. This variant has not been previously described in the medical literature nor is it listed in the population databases, which indicates that it is extremely rare. The treatment focuses on the control of seizures, sleep disturbances, extrapyramidal symptoms, behavioral disorders, anxiety, and psychosis.Conclusion:
To date, this variant of the CLN6 gene has not been reported in the world. There are currently no etiological or disease-specific therapeutic approaches. The use of exome/whole genome sequencing can be very useful for etiological diagnosis and differential diagnosis. An early diagnosis opens the door to future care and treatment.
