Labcorp Genetics (formerly Invitae), Labcorp RCV004579440 SCV005063441 uncertain significance Congenital dyserythropoietic anemia, type II; Cowden syndrome 7 2023-06-14 criteria provided, single submitter clinical testing 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. This variant disrupts a region of the SEC23B protein in which other variant(s) (p.His757Pro) have been observed in individuals with SEC23B-related conditions (PMID: 20941788). 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 SEC23B-related conditions. This variant is a gross deletion of the genomic region encompassing exon(s) 20 of the SEC23B gene, which includes the termination codon. This deletion extends beyond the assayed region for this gene and therefore may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product.
