Table 3. Comparison of the efficiency of mutation detection efficiency using INNOLiPA tests and teh follow-up screening (SSCP/HD and sequencing).

Overall mutations detected in a patient	Proportion of patients	CF mutations per patient detected in INNOLiPA tests	Additional CF alleles detected in the follow-up phase	Number of CF patients
both	78.6%	both	n.a.	503
“	“	one	1	71a

Legend: ^a including six alleles with T₅_TG_12–13 in intron 9; ^b including four alleles with T_5or8_TG_12–13 in intron 9; ^c also analyzed by MLPA
