The c.665G>T (p.R222L) alteration is located in exon 5 (coding exon 5) of the DNAJA4 gene. This alteration results from a G to T substitution at nucleotide position 665, causing the arginine (R) at amino acid position 222 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
