Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM1PM2PP2PP3_Strong

The NM_001080483.3(MYMK):c.542G>C(p.Ser181Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,722 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S181N) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1

In a chain Protein myomaker (size 220) in uniprot entity MYMK_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_001080483.3

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 5 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.76146 (below the threshold of 3.09). Trascript score misZ: 1.1389 (below the threshold of 3.09). GenCC associations: The gene is linked to Carey-Fineman-Ziter syndrome 1, Carey-Fineman-Ziter syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.973
