The c.230T>C (p.I77T) alteration is located in exon 3 (coding exon 3) of the DNAJA4 gene. This alteration results from a T to C substitution at nucleotide position 230, causing the isoleucine (I) at amino acid position 77 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
