Abstract
GLB1 encodes beta-galactosidase-1, a lysosomal hydrolase that cleaves the terminal beta-galactose from ganglioside substrates. Biallelic variants in GLB1 cause beta-galactosidase deficiency leading to GM1 gangliosidosis.1 Type III GM1 gangliosidosis shows extreme clinical variability and is less severe than GM1-gangliosidosis types I and II.2 Here we describe a new family with GM1-gangliosidosis type III extending the geographic range of reported cases to Transcaucasia and expanding the disease phenotype.
