Genetic Variant MROH2B:c.2241+8_2241+9insAATAGATAGATAGATAGATA (chr5-41033829-C-CTATCTATCTATCTATCTATT) – 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+9insAATAGATAGATAGATAGATA variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000325 in 1,324,894 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
