Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.125T>A (p.V42E) alteration is located in exon 1 (coding exon 1) of the UQCRFS1 gene. This alteration results from a T to A substitution at nucleotide position 125, causing the valine (V) at amino acid position 42 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
