ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP3

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

BP4

Computational evidence support a benign effect (MetaRNN=0.36925814).

BS2

High AC in GnomAd4 at 49 AD gene.
