Description

The c.179+1G>C intronic variant results from a G to C substitution one nucleotide after coding exon 3 of the SDHC gene. This variant has been observed in at least one individual with a personal and/or family history that is consistent with SDHC-associated disease (Ambry internal data).This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and may result in the creation or strengthening of a novel splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). Based on the majority of available evidence to date, this variant is likely to be pathogenic.
