Description

The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. The variant has been confirmed to be de novo. In silico tools predict the variant to alter splicing and produce an abnormal transcript (SpliceAI: 0.84). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with ACTB related disorder (ClinVar ID: VCV001177325). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline.
