The c.425T>C (p.V142A) alteration is located in exon 6 (coding exon 5) of the IL34 gene. This alteration results from a T to C substitution at nucleotide position 425, causing the valine (V) at amino acid position 142 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
