Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.842A>T (p.Y281F) alteration is located in exon 6 (coding exon 6) of the COQ5 gene. This alteration results from a A to T substitution at nucleotide position 842, causing the tyrosine (Y) at amino acid position 281 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
