Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000035097 SCV000058737 likely pathogenic 3-Methylglutaconic aciduria type 2 2012-07-24 criteria provided, single submitter clinical testing The Gly197Glu variant in TAZ has been reported in one male infant with clinical features of Barth syndrome and a family history of disease that is consistent wi th X-linked inheritance (Kelley 1991, Johnston 1997). This variant has not been identified in large and broad European American and African American populations by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS). This low frequency is consistent with a disease causing role but insufficient to esta blish this with confidence. Computational analyses (biochemical amino acid prope rties, conservation, PolyPhen2, and SIFT) suggest that this variant may impact t he protein, though this information is not predictive enough to determine pathog enicity. Finally, the majority of TAZ variants are pathogenic (www.barthsyndrome .org) and other variants at this position (Gly197Arg, Gly197Trp, Gly197Val) have been reported in individual's the Barth syndrome. In summary, this variant is l ikely to be pathogenic, though additional studies are required to fully establis h its clinical significance.
