dbSNP rs70988830: MROH2B:c.2241+8_2241+9insAATAGATAGATAGATAGATAGATA (chr5-41033829-C-CTATCTATCTATCTATCTATCTATT) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_173489.5(MROH2B):c.2241+8_2241+9insAATAGATAGATAGATAGATAGATA variant causes a splice region, 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.
