Labcorp Genetics (formerly Invitae), Labcorp RCV003232522 SCV002312391 likely pathogenic Sotos syndrome 2021-08-16 criteria provided, single submitter clinical testing This variant results in a copy number gain of the genomic region encompassing exon(s) 3 of the NSD1 gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be out-of-frame, and may result in an absent or disrupted protein product. Loss-of-function variants in NSD1 are known to be pathogenic (PMID: 12464997, 14571271, 15942875, 16247291). A similar copy number variant has been observed in individual(s) with clinical features of Sotos syndrome (Invitae). 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.
