Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_006532.4(ELL):c.1277G>C(p.Gly426Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000132 in 1,589,460 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. G426S) has been classified as Likely benign.

The c.1277G>C (p.G426A) alteration is located in exon 8 (coding exon 8) of the ELL gene. This alteration results from a G to C substitution at nucleotide position 1277, causing the glycine (G) at amino acid position 426 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
