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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jun 13, 2023	In silico analysis supports that this missense variant does not alter protein structure/function; Observed in an individual with a personal history of chondroma (Yepes et al., 2021); This variant is associated with the following publications: (PMID: 24728327, 26336887, 34070849) -
Uncertain significance, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The SUFU p.R343H variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs79299301), Cosmic and ClinVar (classified as uncertain significance by Ambry Genetics, Invitae, Illumina and Fulgent Genetics). The variant was identified in control databases in 23 of 282820 chromosomes at a frequency of 0.00008132 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Other in 2 of 7224 chromosomes (freq: 0.000277), European (non-Finnish) in 19 of 129150 chromosomes (freq: 0.000147), African in 1 of 24960 chromosomes (freq: 0.00004) and South Asian in 1 of 30616 chromosomes (freq: 0.000033), but was not observed in the Latino, Ashkenazi Jewish, East Asian, or European (Finnish) populations. The p.R343 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Sep 11, 2023	The SUFU c.1028G>A; p.Arg343His variant (rs79299301) is reported in the literature in an individual affected with chordoma, but without clear disease association (Yepes 2021). This variant is also reported in ClinVar (Variation ID: 135285), and is found in the non-Finnish European population with an allele frequency of 0.015% (19/129150 alleles) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.473). Due to limited information, the clinical significance of this variant is uncertain at this time. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
