Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_003802.3(MYH13):​c.5584C>T​(p.His1862Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000291 in 1,613,528 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign 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. H1862Q) has been classified as Uncertain significance.

The c.5584C>T (p.H1862Y) alteration is located in exon 39 (coding exon 37) of the MYH13 gene. This alteration results from a C to T substitution at nucleotide position 5584, causing the histidine (H) at amino acid position 1862 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
