The application relates to a primer group, a kit and a method for detecting a plurality of
disease-
related gene mutation types. The application can simultaneously detect genetic deafness,
thalassemia and
spinal muscular atrophy disease-
related gene mutation types, only needs one tube, and can simultaneously detect clinically common known pathogenic SNPs, INDELs and copy number variations in one experiment, thereby significantly improving the detection efficiency of the three diseases and the
standardization degree of clinical detection. The primer group comprises: 1) a primer for detecting genetic deafness
gene mutation types, as shown in SEQ ID NO: 1-30; 2) a primer for detecting
thalassemia gene mutation types, as shown in SEQ ID NO: 31-340; 3) a primer for detecting
spinal muscular atrophy gene mutation types, as shown in SEQ ID NO: 341-350; and 4) a primer for detecting a beta-
actin housekeeping gene, as shown in SEQ ID NO: 351-352.
