The c.470C>T (p.S157F) alteration is located in exon 3 (coding exon 2) of the ZSCAN21 gene. This alteration results from a C to T substitution at nucleotide position 470, causing the serine (S) at amino acid position 157 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
