Genes affected

LBHD1 (HGNC:28351): (LBH domain containing 1) This gene shares three exons in common with another gene, chromosome 11 open reading frame 98 (GeneID:102288414), but the encoded protein uses a reading frame that is different from that of the chromosome 11 open reading frame 98 gene. [provided by RefSeq, Nov 2017]

LBHD1 links:

UQCC3 (HGNC:34399): (ubiquinol-cytochrome c reductase complex assembly factor 3) Complex III is a mitochondrial inner membrane protein complex that transfers electrons from ubiquinol to cytochrome c. This gene encodes a protein that functions in complex III assembly. Mutations in this gene result in Mitochondrial complex III deficiency, nuclear type 9. [provided by RefSeq, Dec 2014]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with UQCC3-related conditions. This variant is present in population databases (rs775150319, gnomAD 0.04%). This sequence change falls in intron 1 of the UQCC3 gene. It does not directly change the encoded amino acid sequence of the UQCC3 protein. It affects a nucleotide within the consensus splice site. -
