The c.3689A>T (p.E1230V) alteration is located in exon 18 (coding exon 18) of the ZFC3H1 gene. This alteration results from a A to T substitution at nucleotide position 3689, causing the glutamic acid (E) at amino acid position 1230 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
