The c.2205G>T (p.K735N) alteration is located in exon 15 (coding exon 14) of the ZER1 gene. This alteration results from a G to T substitution at nucleotide position 2205, causing the lysine (K) at amino acid position 735 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
