Female with pentsuria. Makes no detectable "x" protein. "X" is the reductase. Parents are third
cousins (Each make -50% of normal "x" protein. Only patient has disorder. No “x" MRNA
present. Genomic DNA analyses shows no “x" DNA sequences and "x"s first and last exon
have no amplification for PCR. Normal shows at 1.9 kb band.
Is mutation because of deletion of promoter, or del. Of whole gene locus? Why?
