The proband AR534-05 had two independent allelic mutations: a 4139CT transition which by conceptual translation results in the missense amino acid substitution of leucine for proline at codon 1380 (P1380L; Fig. 1); and a 2461TA transversion, resulting in a predicted amino acid substitution of arginine for tryptophan at codon 821 (W821R; Fig. 1).

The p.W821R mutation resulting from c.2461T>A transversion was previously reported by Lewis et al. (1999), however in both of our patients thymine at position c.2461 was not substituted by adenine but by cytosine (c.2461T>C).
