RESUMEN
A c.57 C > T mutation in the seed region of MIR184 located at the 15q25.1 chromosomal region has been independently associated with autosomal dominant keratoconus with early-onset anterior polar cataract in the Northern Irish family and with autosomal dominant EDICT (Endothelial Dystrophy, Iris hypoplasia, Congenital cataracts, and stromal Thinning) syndrome. In this study we report a five-generation family originating in Galicia, Spain with early onset cataracts and variable corneal abnormalities which include non-ectatic corneal thinning and severe early-onset keratoconus. We identified a heterozygous c.57 C > T mutation in miR-184 in the proband and two additional affected relatives on the maternal side. This finding represents a third independent occurrence of this mutation in familiar ocular disease thus strengthening the link between miR-184 abnormalities and inherited eye defects.
