Notes
aka c.332A>G (p.Asn111Ser or N111S) The variant allele is mentioned in a 2018 publication as a non-synonymous mutation in the PMEL gene, potentially acting in a dominant manner causing pigment dispersion syndrome (PDS) in the iris, which 15-20% of the time develops into pigmentary glaucoma (PG), a major cause of blindness in young adults.
