Labcorp Genetics (formerly Invitae), Labcorp RCV003111487 SCV003791907 pathogenic Childhood encephalopathy due to thiamine pyrophosphokinase deficiency 2022-08-04 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the TPK1 protein in which other variant(s) (p.Leu142Phe) have been determined to be pathogenic (PMID: 31288420, 31404531; Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with TPK1-related conditions. This variant is a gross deletion of the genomic region encompassing exon(s) 6-7 of the TPK1 gene. This variant would be expected to be in-frame, preserving the integrity of the reading frame.
