Genes affected
LRP12 (HGNC:31708): (LDL receptor related protein 12) This gene encodes a member of the low-density lipoprotein receptor related protein family. The product of this gene is a transmembrane protein that is differentially expressed in many cancer cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]
LRP12 Gene-Disease associations (from GenCC):
  • oculopharyngodistal myopathy 1

The c.2227A>G (p.T743A) alteration is located in exon 7 (coding exon 7) of the LRP12 gene. This alteration results from a A to G substitution at nucleotide position 2227, causing the threonine (T) at amino acid position 743 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
