Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_012081.6(ELL2):c.892G>C(p.Ala298Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 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. A298T) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: ELL2 NM_012081.6 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.17
