Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP4_StrongBP6_ModerateBS2

The NM_002479.6(MYOG):c.440G>A(p.Arg147His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000292 in 1,613,710 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R147C) has been classified as Benign.

Genes affected

MYOG (HGNC:7612): (myogenin) Myogenin is a muscle-specific transcription factor that can induce myogenesis in a variety of cell types in tissue culture. It is a member of a large family of proteins related by sequence homology, the helix-loop-helix (HLH) proteins. It is essential for the development of functional skeletal muscle. [provided by RefSeq, Jul 2008]

MYOG links:

MYOPARR (HGNC:54178): (myogenin promoter associated myogenic regulatory antisense long non coding RNA) Predicted to enable RNA polymerase II core promoter sequence-specific DNA binding activity. Predicted to be involved in myoblast fate specification. Predicted to act upstream of or within with a positive effect on gene expression. Predicted to act upstream of or within protein-containing complex assembly and skeletal muscle fiber development. [provided by Alliance of Genome Resources, Apr 2022]
