Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 03, 2022The c.5T>C (p.L2S) alteration is located in exon 1 (coding exon 1) of the UQCRFS1 gene. This alteration results from a T to C substitution at nucleotide position 5, causing the leucine (L) at amino acid position 2 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
