One key component of our commitment to providing quality genetic testing is to look deeper into technically challenging but clinically important genes and regions not covered by many standard NGS workflows. These technically challenging genes can be responsible for a significant proportion of genetic diseases.
One such gene is RPGR, which accounts for 10–20% of all retinitis pigmentosa diagnoses. The ORF15 exon is a known hotspot for disease-causing variants but is challenging to sequence. Despite its relevance, ORF15 is often excluded because of these challenging regions. At Blueprint Genetics, our aim is to include these challenging regions, increasing the likelihood of detecting pathogenic variants in genes such as RPGR.
