Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PM2 PP2 PP3_Strong PP5_Moderate

The NM_000278.5(PAX2):​c.187G>A​(p.Gly63Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G63D) has been classified as Uncertain significance.

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

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM1: In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_000278.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 28 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 1.4895 (below the threshold of 3.09). Trascript score misZ: 1.8687 (below the threshold of 3.09). GenCC associations: The gene is linked to familial idiopathic steroid-resistant nephrotic syndrome, renal coloboma syndrome, focal segmental glomerulosclerosis 7.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.983
• PP5: Variant 10-100749889-G-A is Pathogenic according to our data. Variant chr10-100749889-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 217287.Status of the report is criteria_provided_single_submitter, 1 stars.
