The invention discloses
gene combinations, a primer, a probe and applications thereof for determining PDS
gene mutation of large
vestibular aqueduct syndrome deafness. The
gene combinations comprise combinations of the following five
mutant sites of PDS genes: IVS7-2A>G, A2168G (H723R), L236P, IVS8 +1 G>A and T416P which are respectively corresponding to the following SNP (
single nucleotide polymorphism) sites: the rs111033313 site, the rs121908362 site, the rs80338848 site, the rs80338849 site and the rs28939086 site. According to the applications disclosed by the invention, a group of genes and sites related to the susceptibility of large
vestibular aqueduct syndrome deafness are detected, and whether the subject
population carry susceptible genes of large
vestibular aqueduct syndrome deafness can be detected and analyzed comprehensively by using a specific primer and a specific probe by a mononucleotide extension technology combined with a
microarray chip technology, thereby screening out
susceptible population of large vestibular
aqueduct syndrome deafness from the subject
population, and achieving the purposes of rapid diagnosis and treatment.
