Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000409898 SCV001338491 pathogenic Glycogen storage disease due to glucose-6-phosphatase deficiency type IA 2020-04-02 criteria provided, single submitter clinical testing Variant summary: G6PC c.980_982delTCT (p.Phe327del) results in an in-frame deletion that is predicted to remove one amino acid from the encoded protein. The variant allele was found at a frequency of 4e-06 in 251410 control chromosomes (gnomAD). c.980_982delTCT (p.Phe327del) has been reported in the literature in multiple individuals (both homozygous and compound heterozygous) affected with Glycogen Storage Disease Type Ia (e.g. Lei_1995, Kishnani_2009). These data indicate that the variant is very likely to be associated with disease. In functional studies, the variant was found to have very low or no enzymatic activity (e.g. Lei_1995, Shieh_2002). Two ClinVar submitters (evaluation after 2014) cite the variant as likely pathogenic/pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
