Age The infantile form (type 1) of G M1 gangliosidosis typically presents from birth to age 6 months, the juvenile form (type 2) typically presents in children aged 1-3 years, and the adult form (type 3) typically presents during childhood or adolescence [emedicine.medscape.com]

Symptoms are often observed around 3 months of age with progressive deterioration occurring between 12 and 18 months of age but visceromegaly, dysmorphisms and cherry-red spots are usually not present. [themedicalbiochemistrypage.org]
