Description

The DHCR7 c.964-1G>T variant is predicted to disrupt the AG splice acceptor site and interfere with normal splicing. This variant was reported in an individual with Smith-Lemli-Opitz syndrome (described as IVS8-1G>T, Jira et al. 2001. PubMed ID: 11427181). This variant is reported in 0.051% of alleles in individuals of European (Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-71146886-C-A). Variants that disrupt the consensus splice acceptor site in DHCR7 are expected to be pathogenic. This variant is interpreted as pathogenic.
