Genetic Variant ARIH1:p.Gly83_Gly86dup (chr15-72474873-T-TGGCGGCGGCGGC) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_005744.5(ARIH1):c.246_257dupCGGCGGCGGCGG(p.Gly83_Gly86dup) variant causes a disruptive inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000425 in 1,413,008 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. G86G) has been classified as Likely benign.
