Among them, there were 13 cases (46.4%) with <jats:italic>ANK1<\/jats:italic> mutation, 10 cases (35.7%) with <jats:italic>SPTB<\/jats:italic> mutation, three cases (10.7%) with <jats:italic>SLC4A1<\/jats:italic> mutation, and two cases (7.2%) with <jats:italic>SPTA1<\/jats:italic> mutation. All mutations cause amino acid changes in the coding gene, as well as subsequent changes in protein structure or loss of function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>All the newly discovered gene coding region mutation sites detected are the suspected pathogenic causes of the 28 Chinese children. At the same time, the second\u2010generation gene sequencing technology is an effective means to diagnose HS. Different mutation types and different mutation regions have no significant correlation with the severity of anemia. The novel gene mutation sites in 28 children studied in this paper have not yet been included in the human genome database, dbSNP (v138), or ExAC database. The new gene mutations found in HS children can provide a theoretical basis for further exploring the genetic causes of HS in Chinese children.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mgg3.1577","type":"journal-article","created":{"date-parts":[[2021,2,23]],"date-time":"2021-02-23T11:56:21Z","timestamp":1614081381000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Clinical
