Genetic Variant NM_001031703.3:c.563C>G (chr3-47498395-G-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001031703.3(ELP6):c.563C>G(p.Ala188Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000273 in 1,613,242 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. A188V) has been classified as Likely benign.

The c.563C>G (p.A188G) alteration is located in exon 6 (coding exon 6) of the ELP6 gene. This alteration results from a C to G substitution at nucleotide position 563, causing the alanine (A) at amino acid position 188 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
