Jun 16, 2023

The c.27G>T (p.L9F) alteration is located in exon 1 (coding exon 1) of the SDHAF4 gene. This alteration results from a G to T substitution at nucleotide position 27, causing the leucine (L) at amino acid position 9 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
