Genes affected

PAX3 (HGNC:8617): (paired box 3) 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. Mutations in paired box gene 3 are associated with Waardenburg syndrome, craniofacial-deafness-hand syndrome, and alveolar rhabdomyosarcoma. The translocation t(2;13)(q35;q14), which represents a fusion between PAX3 and the forkhead gene, is a frequent finding in alveolar rhabdomyosarcoma. Alternative splicing results in transcripts encoding isoforms with different C-termini. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 47 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Gene score misZ: 1.618 (below the threshold of 3.09). Trascript score misZ: 1.7934 (below the threshold of 3.09). GenCC associations: The gene is linked to Waardenburg syndrome type 3, Waardenburg syndrome type 1, Waardenburg syndrome, craniofacial-deafness-hand syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.894

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000222 (324/1461890) while in subpopulation NFE AF = 0.000287 (319/1112010). AF 95% confidence interval is 0.000261. There are 0 homozygotes in GnomAdExome4. There are 150 alleles in the male GnomAdExome4 subpopulation. Median coverage is 35. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
