Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 1P and 16B. PP2BP4_StrongBP6_Very_StrongBS2

The ENST00000265343.10(AFF4):ā€‹c.3319A>Gā€‹(p.Thr1107Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00205 in 1,614,082 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (ā˜…ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T1107I) has been classified as Uncertain significance.

Genes affected
AFF4 (HGNC:17869): (ALF transcription elongation factor 4) The protein encoded by this gene belongs to the AF4 family of transcription factors involved in leukemia. It is a component of the positive transcription elongation factor b (P-TEFb) complex. A chromosomal translocation involving this gene and MLL gene on chromosome 11 is found in infant acute lymphoblastic leukemia with ins(5;11)(q31;q31q23). [provided by RefSeq, Oct 2011]
