The c.26C>T (p.S9F) alteration is located in exon 2 (coding exon 1) of the DNAJC16 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the serine (S) 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. -
