Usher syndrome is a rare disease impacting about 20,000 Americans, according to Jeff Holt, Ph.D., chair of the Usher Syndrome Society’s scientific advisory board.
A mutation on the USH2A gene is known to cause 10-15% of a syndromic form of RP known as Usher's Syndrome when inherited in an autosomal recessive fashion. [23] Mutations in four pre-mRNA splicing factors are known to cause autosomal dominant retinitis pigmentosa. These are PRPF3 (human PRPF3 is HPRPF3; also PRP3), PRPF8, PRPF31 and PAP1.
