Genetic Variant XR_002958413.2:n.483-65719_483-65709dupAAAAAAAAAAA (chr1-189502601-T-TAAAAAAAAAAA) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The XR_002958413.2(LOC105371657):n.483-65719_483-65709dupAAAAAAAAAAA variant causes a intron change involving the alteration of a non-conserved nucleotide. 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
