We report two unrelated individuals with developmental delay, microcephaly, and distinctive facial features, in whom exome sequencing and chromosomal microarray analysis revealed a homozygous deletion of\n                    <jats:italic>PHF20<\/jats:italic>\n                    that segregated with the disease phenotype in their families. Breakpoint junction sequencing revealed an\n                    <jats:italic>Alu\u2013Alu<\/jats:italic>\n                    \u2010mediated deletion event. Western blot in cells from an affected individual showed undetectable PHF20, while levels of other NSL complex subunits were unaltered. Transcriptomic and epigenomic analysis revealed significant downregulation of gene pathways related to cell projection and neuronal development, associated with reduced histone H4K16 acetylation at these genes. In conclusion, our data suggest that homozygous deletion of\n                    <jats:italic>PHF20<\/jats:italic>\n                    leads to a neurodevelopmental syndrome, potentially through targeted epigenetic dysregulation and altered gene expression essential for neuronal development.

studies in neuronal cell lines will be essential for understanding the disease mechanism.\n
