In a normal cell (upper left diagram), the expected FISH signal pattern is two orange probes (CSF1R) and two green probes (D5S23/D5S721). In a hybridized abnormal cell containing the 5q33-­q34 deletion (upper right and below), the one orange, two green signal pattern is observedIn a normal cell (upper left diagram), the expected FISH signal pattern is two orange probes (CSF1R) and two green probes (D5S23/D5S721).

Patient (pictured) and control DNA were amplified by real-time PCR using a single primer set and two fluorogenically-labeled probes specific for the wild-type and V617F mutation on the JAK2 gene. Determination of allele genotype was made by examining the resulting amplification plot and corresponding CT value produced for each samplePatient (pictured) and control DNA were amplified by real-time PCR using a single primer set and two fluorogenically-labeled probes specific for the wild-type and V617F mutation on the JAK2 gene.
