Genetic Variant STARD9:p.Cys144Tyr (chr15-42638072-G-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_020759.3(STARD9):c.431G>A(p.Cys144Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.0000026 in 1,537,020 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 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. C144W) has been classified as Uncertain significance.
