Genes affected

PI4KA (HGNC:8983): (phosphatidylinositol 4-kinase alpha) This gene encodes a phosphatidylinositol (PI) 4-kinase which catalyzes the first committed step in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. The mammalian PI 4-kinases have been classified into two types, II and III, based on their molecular mass, and modulation by detergent and adenosine. The protein encoded by this gene is a type III enzyme that is not inhibited by adenosine. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM1

In a domain PI3K/PI4K catalytic (size 278) in uniprot entity PI4KA_HUMAN there are 7 pathogenic changes around while only 3 benign (70%) in NM_058004.4

PP2

Missense variant where missense usually causes diseases, PI4KA

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, phyloP100way_vertebrate, PrimateAI, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.27490807).
