				This mutation , in exon 10 of the CFTR gene, was detected by direct DNA sequencing and is a single base substitution from a guanine to an adenine at base 1690 of exon 10 of the CFTR gene.  This results in the replacement of a Valine residue by an isoleucine in codon 520.  The patient is a 7 year old boy from India and has an as yet unknown mutation on his other CF chromosome.  We have seen this mutation once in 20 non-[delta]F508 CF chromosomes analysed by direct sequencing.
