Genes affected

PAX7 (HGNC:8621): (paired box 7) 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. The specific function of the paired box 7 gene is unknown but speculated to involve tumor suppression since fusion of this gene with a forkhead domain family member has been associated with alveolar rhabdomyosarcoma. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]

Ambry Genetics

Nov 17, 2022

The c.434G>A (p.R145Q) alteration is located in exon 3 (coding exon 3) of the PAX7 gene. This alteration results from a G to A substitution at nucleotide position 434, causing the arginine (R) at amino acid position 145 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
