Labcorp Genetics (formerly Invitae), Labcorp RCV001320563 SCV001511354 uncertain significance Cerebral creatine deficiency syndrome 2022-07-26 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with aspartic acid, which is acidic and polar, at codon 155 of the GAMT protein (p.His155Asp). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with GAMT-related conditions. ClinVar contains an entry for this variant (Variation ID: 1020905). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
