The c.449C>T (p.A150V) alteration is located in exon 3 (coding exon 1) of the ZCCHC16 gene. This alteration results from a C to T substitution at nucleotide position 449, causing the alanine (A) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
