Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_Moderate BS1

The NM_016169.4(SUFU):​c.1379A>G​(p.Lys460Arg) variant causes a missense change. The variant allele was found at a frequency of 0.000039 in 1,613,960 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K460T) has been classified as Uncertain significance.

Genes affected

SUFU (HGNC:16466): (SUFU negative regulator of hedgehog signaling) The Hedgehog signaling pathway plays an important role in early human development. The pathway is a signaling cascade that plays a role in pattern formation and cellular proliferation during development. This gene encodes a negative regulator of the hedgehog signaling pathway. Defects in this gene are a cause of medulloblastoma. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.2236202).
• BS1: Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000417 (61/1461864) while in subpopulation AMR AF = 0.000291 (13/44724). AF 95% confidence interval is 0.000171. There are 0 homozygotes in GnomAdExome4. There are 26 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
