Genetic Variant NM_001352171.3:c.1175+39_1175+50dupGTGTGTGTGTGT (chr12-104866381-T-TACACACACACAC) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_001352171.3(SLC41A2):c.1175+39_1175+50dupGTGTGTGTGTGT 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.
