Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP3BP6BS2
The NM_002473.6(MYH9):c.5806C>T(p.Arg1936Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000136 in 1,613,392 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1936Q) has been classified as Likely benign.

Submissions by phenotype
not provided Uncertain:1Benign:1
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
- -
not specified Uncertain:1
Variant classified as Uncertain Significance - Favor Benign. The Arg1936Trp vari ant in MYH9 has not been reported in the literature or in large population studi es. The arginine (Arg) residue at position 1936 is not conserved across species , with sloth having a Trp. Although additional information is needed to fully as sess the clinical significance of this variant; the lack of conservation suggest s a more likely benign role. -

Macrothrombocytopenia and granulocyte inclusions with or without nephritis or sensorineural hearing loss Uncertain:1
This MYH9 missense variant (rs727503281) is rare (<0.1%) in a large population dataset (gnomAD: 8/250532 total alleles; 0.003193%; no homozygotes). It has an entry in ClinVar (Variation ID 164412), but has not ben reported in the literature, to our knowledge. Three bioinformatic tools queried predict that this substitution would be deleterious, and the arginine residue at this position is evolutionarily conserved across all species assessed. We consider the clinical significance of c.5806C>T to be uncertain at this time. -
MYH9-related disorder Uncertain:1
The MYH9 c.5806C>T variant is predicted to result in the amino acid substitution p.Arg1936Trp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0098% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Inborn genetic diseases Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
