Description

The c.110_110+1dupGG variant results from a duplication of 2 nucleotides between positions 110 and 110+1 and involves the canonical splice donor site after coding exon 1 of the TCAP gene. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). The canonical splice donor site is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and will result in the creation or strengthening of a novel splice donor site. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic.
