Abstract

A girl, born to unrelated Spanish parents, presented at 6 months of age with photophobia, keratitis, palmar hyperkeratosis and high plasma tyrosine levels, indicative of tyrosinaemia type II. Analysis of the tyrosine aminotransferase (TAT) gene revealed a paternally inherited frameshift mutation c.1213delCinsAG at codon 405 causing a premature stop codon, and a maternally inherited deletion of 193kb encompassing the complete TAT gene and three neighbouring genes. This is the first complete TAT deletion in tyrosinaemia type II described so far.
