This study hypothesized a possible involvement of <jats:styled-content style=\"fixed-case\">TBX22<\/jats:styled-content> in a family with X\u2010linked, <jats:styled-content style=\"fixed-case\">CHARGE<\/jats:styled-content>\u2010like Abruzzo\u2013Erickson syndrome, of unknown etiology. The phenotype extends to additional features including sensorineural deafness and coloboma, which are suggested by the <jats:italic>Tbx22<\/jats:italic> developmental expression pattern but not previously associated in <jats:styled-content style=\"fixed-case\">CPX<\/jats:styled-content> patients. A novel <jats:italic><jats:styled-content style=\"fixed-case\">TBX22<\/jats:styled-content><\/jats:italic> splice acceptor mutation (c.593\u2212<jats:styled-content style=\"fixed-case\">5T<\/jats:styled-content>&gt;A) was identified that tracked with the phenotype in this family. A novel splice donor variant (c.767+<jats:styled-content style=\"fixed-case\">5G<\/jats:styled-content>&gt;A) and a known canonical splice donor mutation (c.767+<jats:styled-content style=\"fixed-case\">1G<\/jats:styled-content>&gt;A) affecting the same exon were identified in patients with classic <jats:styled-content style=\"fixed-case\">CPX<\/jats:styled-content> phenotypes and were comparatively analyzed using both <jats:italic>in silico<\/jats:italic> and <jats:italic>in vitro<\/jats:italic> splicing studies. All three variants were predicted to abolish normal <jats:styled-content style=\"fixed-case\">mRNA<\/jats:styled-content> splicing and an <jats:italic>in vitro<\/jats:italic> assay indicated that use of alternative splice sites was a likely outcome. Collectively, the data showed the functional effect of several novel intronic splice site variants but most importantly confirms that <jats:italic><jats:styled-content
