Genes affected

PAX9 (HGNC:8623): (paired box 9) This gene is a member of the paired box (PAX) family of transcription factors. Members of this gene family typically contain a paired box domain, an octapeptide, and a paired-type homeodomain. These genes play critical roles during fetal development and cancer growth. Mice lacking this gene exhibit impaired development of organs, musculature and the skeleton, including absent and abnormally developed teeth, and neonatal lethality. Mutations in the human gene are associated with selective tooth agenesis-3. [provided by RefSeq, Sep 2015]

ACMG classification

Our verdict: Pathogenic. The variant received 14 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000493910: In vitro experiment confirmed a functional defect of the variant protein.
• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_001372076.1
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.993
• PP5: Variant 14-36662951-C-T is Pathogenic according to our data. Variant chr14-36662951-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 375454.Status of the report is criteria_provided_single_submitter, 1 stars.
