Nov 27, 2023

The c.1196T>G (p.I399S) alteration is located in exon 6 (coding exon 5) of the ZKSCAN8 gene. This alteration results from a T to G substitution at nucleotide position 1196, causing the isoleucine (I) at amino acid position 399 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
