The c.2065C>G (p.L689V) alteration is located in exon 20 (coding exon 20) of the FCHSD1 gene. This alteration results from a C to G substitution at nucleotide position 2065, causing the leucine (L) at amino acid position 689 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
