Genes affected

KLHL40 (HGNC:30372): (kelch like family member 40) This gene encodes a protein containing a BACK domain, a BTB/POZ domain, and 5 Kelch repeats, however, its exact function is not known. The gene and the multi-domain protein structure are conserved across different taxa, including primates, rodents, chicken and zebrafish. [provided by RefSeq, Dec 2012]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.035648078).

BP6

Variant 3-42691889-G-A is Benign according to our data. Variant chr3-42691889-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 474333.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00165 (244/147654) while in subpopulation AFR AF = 0.00531 (198/37258). AF 95% confidence interval is 0.00471. There are 0 homozygotes in GnomAd4. There are 124 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
