8 The most prevalent pathologic variant was the missense mutation p.Leu11Pro. Login to comment
64 Most of the mutations detected have been reported as STGD-associated variants: p.Met1Val, p.Asn96Asp, p.Arg290Trp, p.Val931Met, p.Gly1961Glu, p.Leu2027Phe, p.Arg2030Gln, p.Asp1048fs, and IVS40+5G>A. Login to comment
65 Although most of the mutations were found in one family, five disease-associated alleles were detected in unrelated STGD families (p.Leu11Pro, p.Asp1048fs; p.Gly1961Glu; p.Ser1642Arg; p.Val1681_Cys1685del; p.Val931Met). Login to comment

149 The most frequent mutation found was the missense variant G1961E (6.7%) that, even in the heterozygous state, has been significantly associated with age-related macular degeneration (AMD).16 One missense mutation involving an uncharged amino acid (L11P) in a conserved domain that has been found in FFM patients was detected.

108 In the two 2888delG compound heterozygous families, one of them showed the missense mutation L11P, which affects a conserved amino acid localized in the intracytoplasmic compartment,8 as a second allele, and the other family harbored the L2060R mutation, which produces an alteration in the charge of the mutated amino acid that has been associated with the CRD phenotype.20 In this work, we found that the diagnosis of the proband from family ARDM-79 had changed from arSTGD to arCRD.

91 Almost all disease-associated variants were found in both arSTGD and arCRD phenotypes in our cohort, with the exception of p.Leu11Pro, p.Arg18Trp, p.Ala538Val, and p.Val1973*, which were associated only with CRD. Login to comment
