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 made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000224 (32/1429218) while in subpopulation MID AF= 0.00127 (7/5520). AF 95% confidence interval is 0.000595. There are 0 homozygotes in gnomad4_exome. There are 23 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 03, 2016The c.1174-3delT variant in PAX3 has not been previously reported in individuals with hearing loss, but has been identified in 1/10046 of South Asian chromosome s by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbS NP rs749733628). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. The c.1174-3delT variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. However, this information is not predictive enough to rul e out pathogenicity. In summary, the clinical significance of the c.1174-3delT v ariant is uncertain. -
