Genes affected

PAX1 (HGNC:8615): (paired box 1) This gene is a member of the paired box (PAX) family of transcription factors. Members of the PAX family typically contain a paired box domain and a paired-type homeodomain. These genes play critical roles during fetal development. This gene plays a role in pattern formation during embryogenesis and may be essential for development of the vertebral column. This gene is silenced by methylation in ovarian and cervical cancers and may be a tumor suppressor gene. Mutations in this gene are also associated with vertebral malformations.

This sequence change creates a premature translational stop signal (p.Ser9Argfs*94) in the PAX1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PAX1 are known to be pathogenic (PMID: 1889089, 23851939, 28657137, 29681087). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PAX1-related conditions. For these reasons, this variant has been classified as Pathogenic. -
