Genes affected
PLEKHG5 (HGNC:29105): (pleckstrin homology and RhoGEF domain containing G5) This gene encodes a protein that activates the nuclear factor kappa B (NFKB1) signaling pathway. Mutations in this gene are associated with autosomal recessive distal spinal muscular atrophy. Multiple transcript variants encoding different isoforms have been found for this gene.

Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 1-6469545-A-G is Benign according to our data. Variant chr1-6469545-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 194777.
BP7
Synonymous conserved (PhyloP=-1.32 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0014 (213/152362) while in subpopulation AFR AF = 0.00493 (205/41592). AF 95% confidence interval is 0.00438. There are 0 homozygotes in GnomAd4. There are 86 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
