GM00637

GM00637 (GM637, CVCL_7297) is an SV40-transformed human skin fibroblast cell line from a healthy 18-year-old Puerto Rican female, ALT-positive, used as a normal-fibroblast control in DNA repair, toxicology, and plasma cytotoxicity studies.

GM01650

GM01650 (RRID:CVCL_7328) is a finite human skin fibroblast cell line from a 37-year-old Caucasian woman, held in Coriell's NIGMS Apparently Healthy Collection and used as an unaffected control in genetic disease studies.

GM1 gangliosidosis

GM1 gangliosidosis (beta-galactosidase-1 deficiency, Landing disease) is a rare autosomal recessive lysosomal storage disorder caused by GLB1 variants, with infantile, late-infantile/juvenile, and adult types, and no approved disease-modifying therapy.

GM12878

GM12878 (NA12878) is an EBV-immortalized human lymphoblastoid B cell line from a female HapMap donor of European ancestry, a Coriell-distributed ENCODE Tier 1 line and Genome in a Bottle reference standard for sequencing calibration.

GM2 gangliosidosis, AB variant

GM2 gangliosidosis, AB variant (GM2 activator deficiency, OMIM 272750) is an ultra-rare autosomal recessive lysosomal storage disorder: GM2A mutations disable the GM2 activator protein, so GM2 ganglioside accumulates despite normal hexosaminidase A and B, causing infantile Tay-Sachs-like neurodegeneration.

GM3 synthase deficiency

GM3 synthase deficiency, also called Amish infantile epilepsy syndrome, salt & pepper syndrome, or ST3GAL5-CDG, is an autosomal recessive congenital disorder of glycosylation causing infantile refractory epilepsy, developmental stagnation, deafness, and skin pigment changes.
