Abstract
OBJECTIVE To determine the incidence of congenital hearing loss (HL) in newborns by the rate of deafness-related genetic mutations. DESIGN Clinical study of consecutive newborns in Beijing using allele-specific polymerase chain reaction-based universal array. STUDY SAMPLE This study tested 37 573 newborns within 3 days after birth, including nine sites in four genes: GJB2 (35 del G, 176 del 16, 235 del C, 299 del AT), SLC26A4 (IVS7-2 A > G, 2168 A > G), MTRNR1 (1555 A > G, 1494 C > T), and GJB3 (538 C > T). The birth condition of infants was also recorded. RESULTS Of 37 573 newborns, 1810 carried pathogenic mutations, or 4.817%. The carrier rates of GJB2 (35 del G, 176 del 16, 235 del C, 299 del AT), GJB3 (538 C > T), SLC26A4 (IVS7-2 A > G, 2168 A > G), and MTRNR1 (1555 A > G, 1494 C > T) mutations were 0.005%, 0.104%, 1.924%, 0.551%, 0.295%, 0.253%, 1.387%, 0.024%, and 0.274%, respectively. Logistic regression analysis indicated no statistically significant relationship between mutations and infant sex, premature delivery, twin status, or birth weight. CONCLUSIONS The 235delC GJB2 mutation was the most frequent deafness-related mutation in the Chinese population. Genetic screening for the deafness gene will help detect more cases of newborn congenital HL than current screening practices.

Abstract
Hearing loss (HL) is one of the most common birth defects in developed countries and is a diverse pathologic condition with different classifications. One of these is based on the association with other clinical features, defined as syndromic hearing loss (SHL). Determining the cause of the HL in these patients is extremely beneficial as it enables a personalized approach to caring for the individual. Early screening can further aid in optimal rehabilitation for a child's development and growth. The advancement of high-throughput sequencing technology is facilitating rapid and low-cost diagnostics for patients with SHL.
