Genes affected
MYF6 (HGNC:7566): (myogenic factor 6) The protein encoded by this gene is a probable basic helix-loop-helix (bHLH) DNA binding protein involved in muscle differentiation. The encoded protein likely acts as a heterodimer with another bHLH protein. Defects in this gene are a cause of autosomal dominant centronuclear myopathy (ADCNM). [provided by RefSeq, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.352C>G (p.R118G) alteration is located in exon 1 (coding exon 1) of the MYF6 gene. This alteration results from a C to G substitution at nucleotide position 352, causing the arginine (R) at amino acid position 118 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Autosomal dominant centronuclear myopathy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 18, 2022In 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 837609). This variant has not been reported in the literature in individuals affected with MYF6-related conditions. This variant is present in population databases (rs34563783, gnomAD 0.008%). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 118 of the MYF6 protein (p.Arg118Gly). -
