Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP3
The NM_032578.4(MYPN):c.3263G>A(p.Arg1088His) variant causes a missense change. The variant allele was found at a frequency of 0.00000868 in 1,613,674 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. R1088C) has been classified as Uncertain significance.
