Invitae | RCV003232339 | SCV001577026 | likely pathogenic | Sotos syndrome | 2020-03-10 | criteria provided, single submitter | clinical testing | This variant results in a copy number gain of the genomic region encompassing exon 6 of the NSD1 gene. While the exact position of this variant cannot be determined from this data, sub-genic copy number gains are generally in tandem (PMID: 25640679) and may result in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with NSD1-related conditions. Loss-of-function variants in NSD1 are known to be pathogenic (PMID: 12464997, 14571271, 15942875, 16247291). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
