Labcorp Genetics (formerly Invitae), Labcorp RCV001045494 SCV001209349 likely pathogenic Granulomatous disease, chronic, autosomal recessive, cytochrome b-positive, type 3 2020-01-31 criteria provided, single submitter clinical testing 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. Loss-of-function variants in NCF4 are known to be pathogenic (PMID: 16880254, 19692703, 20167518). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with NCF4-related conditions. This variant is not present in population databases (ExAC no frequency). This variant results in the deletion of part of exon 3 (c.270_271+16del) of the NCF4 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
