CELSR1 and congenital rubella syndrome: Assuming no overlap in the cohorts included in Table 1, 8 PCP genes (VANGL1-2, CELSR1-3, DVL3, SCRIB1 and PTK7) have been re-sequenced in a couple of hundred of CRS cases and no obvious loss of function (LoF) variant was identified in these genes in the majority of CRS cases analyzed.
