Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PM5PP3_Moderate

The NM_001303457.2(TTI1):c.2761G>T(p.Asp921Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000012 in 1,505,208 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D921N) has been classified as Likely pathogenic.
