Genes affected
KLHL41 (HGNC:16905): (kelch like family member 41) This gene is a member of the kelch-like family. The encoded protein contains a BACK domain, a BTB/POZ domain, and 5 Kelch repeats. This protein is thought to function in skeletal muscle development and maintenance. Mutations in this gene have been associated with nemaline myopathy (NM), a rare congenital muscle disorder.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 2-169520867-T-C is Benign according to our data. Variant chr2-169520867-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 474865.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.056 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000361 (55/152350) while in subpopulation AMR AF = 0.000719 (11/15308). AF 95% confidence interval is 0.000402. There are 1 homozygotes in GnomAd4. There are 18 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 3 AR,AD gene
