The c.146T>C (p.V49A) alteration is located in exon 2 (coding exon 2) of the ZCCHC4 gene. This alteration results from a T to C substitution at nucleotide position 146, causing the valine (V) at amino acid position 49 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
