Labcorp Genetics (formerly Invitae), Labcorp RCV001974141 SCV002259165 uncertain significance Progressive sclerosing poliodystrophy 2023-10-13 criteria provided, single submitter clinical testing This variant, c.155_156insTCA, results in the insertion of 1 amino acid(s) of the POLG protein (p.Gln51_Gln52insHis), but otherwise preserves the integrity of the reading frame. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with POLG-related conditions. ClinVar contains an entry for this variant (Variation ID: 1478344). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
