From GMS Respiratory Specialist Test Group webex call 18th Jan 2019 : Hannah Mitchison commented that a subset of PCD genes (DNAJB13, HYDIN, CCDC65, CCNO, DRC1, GAS8, RSPH1, RSPH3, RSPH9, RSPH4A) are NOT associated with laterality disorders and should therefore be red on this panel. Hannah Mitchison to follow up with reference/confirm genes that should be downgraded to Red from Green. However, it was further noted that CCDC65 should be Amber on this panel, as other genes in this family are reliably associated with laterality defects and therefore this may reflect a lack of evidence in this case.
