[Result of Sanger sequencing for newborn carriers of single heterozygous variants of GJB2 or SLC26A4 gene by genechip analysis].

For newborns carrying single heterozygous variants of the GJB2 or SLC26A4 gene by genechip analysis, the detection rate for other variants is quite high. Sanger sequencing can significantly improve the detection rate of high-risk newborns and enrich the variant spectrum of deafness genes.
