RCV002646986 | SCV002980108 | uncertain significance | not provided | 2021-12-12 | criteria provided, single submitter | clinical testing | This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change falls in intron 27 of the HSPG2 gene. It does not directly change the encoded amino acid sequence of the HSPG2 protein. It affects a nucleotide within the consensus splice site. This variant has not been reported in the literature in individuals affected with HSPG2-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. |
Ambry Genetics | RCV002646985 | SCV003580581 | uncertain significance | Inborn genetic diseases | 2021-10-19 | criteria provided, single submitter | clinical testing | The c.3529-3C>T intronic alteration consists of a C to T substitution 3 nucleotides before exon 27 of the HSPG2 gene. Based on data from gnomAD, the T allele has an overall frequency of <0.01% (2/249902) total alleles studied. The highest observed frequency was 0.01% (2/34526) of Latino alleles. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
