Updated version of XLRP test

X-linked retinitis pigmentosa test has come through a profound update. In addition to analysis of 187 mutations in the RP2 and RPGR genes by APEX technology, the testing now includes mutation detection in the ORF15 region, as well as exon 15a and exon 15b deletions in the RPGR gene. The ORF15 region is detected by Sanger sequencing and can be ordered separately.
