Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The NM_001352754.2(ARMC9):​c.539T>A​(p.Ile180Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 1 in 152,354 control chromosomes in the GnomAD database, including 76,156 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I180E) has been classified as Benign.
