Ambry Genetics

Sep 26, 2022

The c.106C>G (p.L36V) alteration is located in exon 1 (coding exon 1) of the NDUFAB1 gene. This alteration results from a C to G substitution at nucleotide position 106, causing the leucine (L) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
