Genes affected

PAX2 (HGNC:8616): (paired box 2) PAX2 encodes paired box gene 2, one of many human homologues of the Drosophila melanogaster gene prd. The central feature of this transcription factor gene family is the conserved DNA-binding paired box domain. PAX2 is believed to be a target of transcriptional supression by the tumor suppressor gene WT1. Mutations within PAX2 have been shown to result in optic nerve colobomas and renal hypoplasia. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2014]

ACMG classification

Verdict is Pathogenic. Variant got 16 ACMG points.

• PM1: In a DNA_binding_region Paired (size 126) in uniprot entity PAX2_HUMAN there are 41 pathogenic changes around while only 0 benign (100%) in NM_000278.5
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.985
• PP5: Variant 10-100750720-C-T is Pathogenic according to our data. Variant chr10-100750720-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 465775.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-100750720-C-T is described in Lovd as [Likely_pathogenic].
