Genetic Variant INO80C:p.Gly53Asp (chr18-35480562-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_194281.4(INO80C):c.158G>A(p.Gly53Asp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000431 in 1,601,690 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. 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. G53S) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.266G>A (p.G89D) alteration is located in exon 4 (coding exon 4) of the INO80C gene. This alteration results from a G to A substitution at nucleotide position 266, causing the glycine (G) at amino acid position 89 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
