Green List (high evidence)

Comment on list classification: Rating Amber but may be promoted to Green at the next GMS panel update (added for-review' tag).

Sufficient number of unrelated cases (3) with microcephaly of relevant severity to this panel (more than -3 SD). Truncating variants appear to be associated with a more severe disease presentation (PMID: 33397746).

Currently not associated with any phenotype in OMIM (last updated on 09/12/2011), but has a 'possible' disease confidence rating for 'Autosomal Recessive Mental Retardation' in Gene2Phenotype.

- 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
