Variant 17-10306572-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PP3_Moderate

The NM_003802.3(MYH13):c.5353C>T(p.Arg1785Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000929 in 1,613,920 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. R1785Q) has been classified as Uncertain significance.

Ambry Genetics

Oct 17, 2023

The c.5353C>T (p.R1785W) alteration is located in exon 37 (coding exon 35) of the MYH13 gene. This alteration results from a C to T substitution at nucleotide position 5353, causing the arginine (R) at amino acid position 1785 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
