ABSTRACT
Nail-Patella Syndrome (NPS) is a rare autosomal dominant condition comprising nail and skeletal anomalies. Skeletal features include dysplastic patellae and iliac horns, as well as scapula and elbow dysplasia. Nephropathy and glaucoma or intra-ocular hypertension can sometimes be present. NPS is due to variants affecting function in LMX1B, which encodes a LIM-homeodomain protein critical for limb, kidney and eye development. We describe the phenotype and the molecular data of 55 index patients and their 39 relatives presenting with typical NPS. We identified 38 different LMX1B anomalies, 19 of which were not reported before. In our series, 9% of families are not carriers of a LMX1B genomic alteration after extensive study of the coding and non-coding regions of the gene. One of the families showed no linkage to the LMX1B locus, raising the hypothesis of a genetic heterogeneity.
