Genes affected
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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.223G>T (p.A75S) alteration is located in exon 2 (coding exon 2) of the UQCC3 gene. This alteration results from a G to T substitution at nucleotide position 223, causing the alanine (A) at amino acid position 75 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
