PLAC4
Chr 21placenta enriched 4
Also known as: C21orf115, PRED78
Based on the provided information, PLAC4 is predicted to encode a protein located in the plasma membrane. However, there is insufficient data provided about associated diseases, inheritance patterns, or clinical phenotypes to generate a meaningful clinical gene summary for a pediatric neurogenetics portal. Additional clinical and genetic information would be needed to create an appropriate summary for child neurologists.
Population Genetics & Constraint
Constraint data not available from gnomAD.
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
