Variant 17-10445274-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP3BS2

The NM_017533.2(MYH4):c.5258G>T(p.Arg1753Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000217 in 1,614,176 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. R1753C) has been classified as Uncertain significance.

Ambry Genetics

Jan 23, 2024

The c.5258G>T (p.R1753L) alteration is located in exon 36 (coding exon 34) of the MYH4 gene. This alteration results from a G to T substitution at nucleotide position 5258, causing the arginine (R) at amino acid position 1753 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
