Sarah Leigh edited their review of gene: RUSC2: Added comment: Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen. At least 2 variants reported in at least 2 unrelated cases. No functional studies have been reported, although authors of PMID 27612186 suggest that p.R866* results in total loss of function as the sibs biallelic with this variant have a more severe phenotype than the case who is biallelic for p.R1318*, which they conclude results in partial loss of function. Refractory seizures were seen in the sibs with p.R866*.; Changed rating: RED
