Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2023The c.233A>T (p.Y78F) alteration is located in exon 2 (coding exon 2) of the UQCRFS1 gene. This alteration results from a A to T substitution at nucleotide position 233, causing the tyrosine (Y) at amino acid position 78 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
