Malformations of cortical development v7.34 ZNF865 Ida Ertmanska Classified gene: ZNF865 as Amber List (moderate evidence)
Malformations of cortical development v7.34 ZNF865 Ida Ertmanska Added comment: Comment on list classification: There are 8 individuals reported in literature with heterozygous ZNF865 variants and brain abnormalities, including hypoplasia of corpus callosum and ventriculomegaly. Based on available evidence, this gene should be promoted to Green at the next GMS update.

Report of 18 unrelated individuals (Caucasian / Latino ethnicity) with developmental delay and shared dysmorphic features, harbouring heterozygous variants in ZNF865. Method: WGS / WES. Majority described as severely delayed, with speech delay and moderate to severe learning difficulties; avg age of walking = 24 months, 9/18 patients presented with hypotonia, 1 patient diagnosed with epilepsy, 9/15 had digit anomalies.
On MRI, 8/14 patients had brain abnormalities, including hypoplasia of corpus callosum and ventriculomegaly. Shared dysmorphic features: broad nasal bridge, hypertelorism, low-set ears.
14 unique variants (nonsense of frameshift) were detected, mostly towards the C-terminus. Variants were confirmed as de novo in 15 individuals.

This gene is not yet linked to any phenotype in OMIM (accessed 10th Mar 2026).
