Genes affected
ACTN4 (HGNC:166): (actinin alpha 4) Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a nonmuscle, alpha actinin isoform which is concentrated in the cytoplasm, and thought to be involved in metastatic processes. Mutations in this gene have been associated with focal and segmental glomerulosclerosis. [provided by RefSeq, Jul 2008]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.41).
BP6
Variant 19-38725729-C-T is Benign according to our data. Variant chr19-38725729-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 585360.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-2.95 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.001 (153/152334) while in subpopulation AFR AF = 0.00349 (145/41572). AF 95% confidence interval is 0.00302. There are 0 homozygotes in GnomAd4. There are 73 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 153 AD gene.
