Genes affected

ACTB (HGNC:132): (actin beta) This gene encodes one of six different actin proteins. Actins are highly conserved proteins that are involved in cell motility, structure, integrity, and intercellular signaling. The encoded protein is a major constituent of the contractile apparatus and one of the two nonmuscle cytoskeletal actins that are ubiquitously expressed. Mutations in this gene cause Baraitser-Winter syndrome 1, which is characterized by intellectual disability with a distinctive facial appearance in human patients. Numerous pseudogenes of this gene have been identified throughout the human genome. [provided by RefSeq, Aug 2017]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000547 (613/1121630) while in subpopulation MID AF= 0.000936 (3/3206). AF 95% confidence interval is 0.00058. There are 0 homozygotes in gnomad4_exome. There are 294 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High AC in GnomAdExome4 at 613 AD gene.
