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.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PM4
Nonframeshift variant in NON repetitive region in NM_006063.3. Strenght limited to Supporting due to length of the change: 1aa.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000472 (69/1461800) while in subpopulation AMR AF = 0.000335 (15/44724). AF 95% confidence interval is 0.000206. There are 0 homozygotes in GnomAdExome4. There are 32 alleles in the male GnomAdExome4 subpopulation. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This variant, c.433_435del, results in the deletion of 1 amino acid(s) of the KLHL41 protein (p.Leu145del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs760524187, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with KLHL41-related conditions. ClinVar contains an entry for this variant (Variation ID: 474872). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
