The c.694G>T (p.A232S) alteration is located in exon 2 (coding exon 2) of the SEZ6L gene. This alteration results from a G to T substitution at nucleotide position 694, causing the alanine (A) at amino acid position 232 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
