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.

Collection Method: clinical testing

The c.153G>T (p.L51F) alteration is located in exon 1 (coding exon 1) of the KLHL41 gene. This alteration results from a G to T substitution at nucleotide position 153, causing the leucine (L) at amino acid position 51 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
