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

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.85).
BP6
Variant 7-5529145-G-A is Benign according to our data. Variant chr7-5529145-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 379757.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0104 (1591/152308) while in subpopulation AFR AF = 0.0367 (1526/41548). AF 95% confidence interval is 0.0352. There are 38 homozygotes in GnomAd4. There are 777 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 1591 AD gene.
