Collection Method:clinical testing

The c.613T>C (p.S205P) alteration is located in exon 5 (coding exon 4) of the HMGXB4 gene. This alteration results from a T to C substitution at nucleotide position 613, causing the serine (S) at amino acid position 205 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
