Genetic Variant MAML3:p.Gln498_Gln509del (chr4-139889909-TTGCTGCTGCTGCTGCTGCTGCTGCTGCTGCTGCTGC-T) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP3BS2

The NM_018717.5(MAML3):c.1491_1526delGCAGCAGCAGCAGCAGCAGCAGCAGCAGCAGCAGCA(p.Gln498_Gln509del) variant causes a disruptive inframe deletion change. The variant allele was found at a frequency of 0.000021 in 1,476,562 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 DEL_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.
