A C to T transversion in codon 771 (exon 23) resulted in the substitution of Arg with Trp (R771W), a mutation initially identified in a patient with symptoms similar to Bloom's syndrome. Sequence analysis of RT-PCR products confirmed that the point mutation in exon 23 was the only change in the coding region of the endogenous gene. (J:77902)
