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 in gene, where missense usually causes diseases (based on misZ statistic), PI4KA. . Gene score misZ 3.5271 (greater than the threshold 3.09). Trascript score misZ 4.6291 (greater than threshold 3.09). GenCC has associacion of gene with polymicrogyria, perisylvian, with cerebellar hypoplasia and arthrogryposis.

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).
