The c.556C>T (p.R186W) alteration is located in exon 5 (coding exon 5) of the DNAJA4 gene. This alteration results from a C to T substitution at nucleotide position 556, causing the arginine (R) at amino acid position 186 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
