Abstract

A maternally inherited novel pathogenic non-POU domain-containing octamer-binding gene variant c.767G>T, p.R256I [NM_001145408], manifested in a male infant as dilated cardiomyopathy with severe left ventricular dysfunction and dilation, biventricular non-compaction, tricuspid hypoplasia, and hydrocephaly. To the best of our knowledge, no previous non-POU domain-containing octamer-binding gene variants with biventricular non-compaction have been associated with tricuspid valve hypoplasia. Hence, this case introduces a new pathogenic variant observed in the non-POU domain-containing octamer-binding gene and adds to the range of cardiac phenotypes identified in non-POU domain-containing octamer-binding gene variants.
