RCV004582042 | SCV005067389 | pathogenic | Hereditary factor IX deficiency disease; Thrombophilia, X-linked, due to factor 9 defect | 2023-03-02 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 6 of the F9 gene. This deletion is out-of-frame, and is expected to create a premature termination codon and result in an absent or disrupted protein product. Loss-of-function variants in F9 are known to be pathogenic (PMID: 20301668). A similar copy number variant has been observed in individuals with hemophilia B (PMID: 23093250, 32875744). For these reasons, this variant has been classified as Pathogenic. |
