Interestingly, a mutation of different codon, i.e., p.Arg58His in CRYGD has been reported to be linked with aculeiform cataract in four different families; two from Switzerland, one from Macedonia and in a Mexican family.
Direct sequencing of the candidate CRYGA-CRYGD gene cluster revealed a c.470G>A transversion in exon 3 of CRYGC, which cosegregated with cataracts in the family and was not observed in 100 normal controls.

This is the first case of phenotypic heterogeneity in the primary congenital cataract specifically associated with the R168W mutation in the CRYGC gene.
