Dyspnea and situs inversus in a boy aged 3 days

Abstract

A boy was admitted on day 3 after birth due to shortness of breath for 2 days and cyanosis for 1 day. He had clinical manifestations of dyspnea in the early postnatal period and situs inversus, and was finally diagnosed with Kartagener syndrome. His condition was improved after oxygen therapy, anti-infective therapy, and aerosol therapy. The genetic testing showed that there was a large-fragment loss of heterozygosity, exon 48_50, and a hemizygous mutation, c.7915C > T(p.R2639X), in the DNAH5 gene. Kartagener syndrome is a rare autosomal recessive disease, and this is the first case of Kartagener syndrome diagnosed in the neonatal period in China.
