The c.609C>G (p.I203M) alteration is located in exon 5 (coding exon 5) of the DNAJA4 gene. This alteration results from a C to G substitution at nucleotide position 609, causing the isoleucine (I) at amino acid position 203 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
