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 -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009362847).

BP6

Variant 3-42690989-C-A is Benign according to our data. Variant chr3-42690989-C-A is described in ClinVar as Benign. ClinVar VariationId is 262642.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000985 (150/152244) while in subpopulation SAS AF = 0.0208 (100/4818). AF 95% confidence interval is 0.0175. There are 3 homozygotes in GnomAd4. There are 94 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
