Labcorp Genetics (formerly Invitae), Labcorp RCV004582530 SCV005067891 pathogenic Biotin-responsive basal ganglia disease 2024-01-09 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exon(s) 5 of the SLC19A3 gene. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to disrupt the C-terminus of the protein. A similar copy number variant has been observed in individual(s) with SLC19A3-related conditions (PMID: 23482991, 24372704). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as p.Q393*fs. For these reasons, this variant has been classified as Pathogenic.
