PHYHIP
Chr 8phytanoyl-CoA 2-hydroxylase interacting protein
Also known as: DYRK1AP3, PAHX-AP, PAHXAP1
The PHYHIP protein enables protein tyrosine kinase binding and is involved in protein localization within the cytoplasm, with its interaction with PHYH suggesting a role in central nervous system development. This gene is highly constrained against loss-of-function variants (pLI 0.86, LOEUF 0.44), indicating that mutations are likely to cause significant developmental effects. However, specific disease associations and inheritance patterns for PHYHIP mutations have not yet been established in the clinical literature.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Highly missense-constrained (top ~0.1%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
