Genes affected

PRRX1 (HGNC:9142): (paired related homeobox 1) The DNA-associated protein encoded by this gene is a member of the paired family of homeobox proteins localized to the nucleus. The protein functions as a transcription co-activator, enhancing the DNA-binding activity of serum response factor, a protein required for the induction of genes by growth and differentiation factors. The protein regulates muscle creatine kinase, indicating a role in the establishment of diverse mesodermal muscle types. Alternative splicing yields two isoforms that differ in abundance and expression patterns. [provided by RefSeq, Jul 2008]

The PRRX1 c.529C>G variant is predicted to result in the amino acid substitution p.Gln177Glu. This variant was reported in an individual with Atrial fibrillation, increased susceptibility (Table S1, Lin et al 2014. PubMed ID: 24239840). This variant is reported in 0.0015% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-170695472-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
