ACTB encodes β-cytoplasmic actin, an essential component of the cytoskeleton. Based on chromosome 7p22.1 deletions that include the ACTB locus and on rare truncating ACTB variants, a phenotype resulting from ACTB haploinsufficiency was recently proposed. We report putative ACTB loss-of-function variants in four patients. To the best of our knowledge, we report the first 7p22.1 microdeletion confined to ACTB and...
