The c.1606C>G (p.Q536E) alteration is located in exon 16 (coding exon 16) of the FCHSD1 gene. This alteration results from a C to G substitution at nucleotide position 1606, causing the glutamine (Q) at amino acid position 536 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
