The c.583G>T (p.V195F) alteration is located in exon 4 (coding exon 4) of the ZNRF3 gene. This alteration results from a G to T substitution at nucleotide position 583, causing the valine (V) at amino acid position 195 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
