- PMID: 33397746 (2021) - Five individuals from four unrelated families with homozygous ZNF526 variants. Four harboured truncating variants, and were all affected by profound DD and severe ID, microcephaly (ranging from -4 SD to -8 SD), bilateral progressive cataracts, hypertonic-dystonic movements, epilepsy and brain MRI anomalies. The fifth patient had a homozygous missense variant and a slightly less severe disorder, with postnatal microcephaly (-2 SD), progressive bilateral cataracts, severe ID, and normal brain MRI. Zebrafish model demonstrated brain and eye malformations resembling findings seen in the human holoprosencephaly spectrum
