Invitae | RCV000708038 | SCV000837148 | uncertain significance | Rubinstein-Taybi syndrome due to CREBBP mutations | 2018-07-03 | criteria provided, single submitter | clinical testing | This variant results in a copy number gain of the genomic region encompassing exon 1 of the CREBBP gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 1 of the CREBBP gene. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. A similar copy number gain affecting the first exon of CREBBP has been observed in an individual affected with Rubinstein-Taybi Syndrome (PMID: 15706485). Experimental studies are not available for this variant and the functional significance of a copy number gain of exon 1 is currently unknown. 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. |
