Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_Strong BP6 BS1

The NM_016169.4(SUFU):c.1158-10C>T variant causes a splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,884 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

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

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BP6: Variant 10-102617280-C-T is Benign according to our data. Variant chr10-102617280-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 413916.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000041 (6/1461884) while in subpopulation AMR AF= 0.000112 (5/44724). AF 95% confidence interval is 0.0000436. There are 0 homozygotes in gnomad4_exome. There are 0 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
