The c.1181C>T (p.S394L) alteration is located in exon 7 (coding exon 6) of the HMGXB3 gene. This alteration results from a C to T substitution at nucleotide position 1181, causing the serine (S) at amino acid position 394 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
