Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_176791.4(GTSF1L):​c.304G>T​(p.Asp102Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 14/21 in silico tools predict a benign 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. D102N) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: GTSF1L NM_176791.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.785
