Description

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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. ClinVar contains an entry for this variant (Variation ID: 56411). This variant is also known as c.-588T>A. This variant has been observed in individual(s) with GRACILE syndrome (PMID: 12215968, 22277166). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This variant occurs in a non-coding region of the BCS1L gene. It does not change the encoded amino acid sequence of the BCS1L protein.
