Foundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human Genetics RCV000984877 SCV001132759 likely pathogenic Infantile GM1 gangliosidosis 2019-10-21 criteria provided, single submitter clinical testing A homozygous missense variation in exon 3 of the GLB1 gene that results in the amino acid substitution of Glutamine for Glutamic acid at codon 129 was detected. The observed variant c.385G>C (p.Glu129Gln) has not been reported in the 1000 genomes and ExAC databases. The in silico prediction of the variant are possibly damaging by PolyPhen-2 (HumDiv) and damaging by SIFT, LRT and MutationTaster2. The reference codon is conserved across species. The observed variant lies in the glycosyl hydrolases family 35 domain of the GLB1 protein and has previously been reported as one of the compound heterozygous variants, in a patient affected with GM1 gangliosidosis (Bidchol et al., 2015). In summary, the variant meets our criteria to be classified as likely pathogenic.
