The purpose was to detect the pathogenic variants in a Chinese family with HTX and CHD. A non-consanguineous Han Chinese family with HTX and CHD, and 200 unrelated healthy subjects were enlisted. Exome sequencing and Sanger sequencing were applied to identify the genetic basis of the HTX family. Compound heterozygous variants, c.3426-1G&gt;A and c.4306C&gt;T (p.(Arg1436Trp)), in the dynein axonemal heavy chain 11 gene (<jats:italic>DNAH11<\/jats:italic>) were identified in the proband via exome sequencing and further confirmed by Sanger sequencing. Neither c.3426-1G&gt;A nor c.4306C&gt;T variant in the <jats:italic>DNAH11<\/jats:italic> gene was detected in 200 healthy controls. The <jats:italic>DNAH11<\/jats:italic> c.3426-1G&gt;A variant was predicted as altering the acceptor splice site and most likely affecting splicing. The <jats:italic>DNAH11<\/jats:italic> c.4306C&gt;T variant was predicted to be damaging, which may reduce the phenotype severity. The compound heterozygous variants, c.3426-1G&gt;A and c.4306C&gt;T, in the <jats:italic>DNAH11<\/jats:italic> gene might be the pathogenic alterations resulting in HTX and CHD in this family. These findings broaden the variant spectrum of the <jats:italic>DNAH11<\/jats:italic> gene and increase knowledge used in genetic counseling for the HTX family.<\/jats:p>","DOI":"10.1371\/journal.pone.0252786","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T17:29:18Z","timestamp":1623864558000},"page":"e0252786","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":20,"title":["DNAH11
