The c.529G>T (p.V177L) alteration is located in exon 5 (coding exon 4) of the DNASE1L2 gene. This alteration results from a G to T substitution at nucleotide position 529, causing the valine (V) at amino acid position 177 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
