Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 29, 2024The c.826G>A (p.G276R) alteration is located in exon 6 (coding exon 6) of the COQ5 gene. This alteration results from a G to A substitution at nucleotide position 826, causing the glycine (G) at amino acid position 276 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
