The c.694G>T (p.D232Y) alteration is located in exon 2 (coding exon 2) of the SPESP1 gene. This alteration results from a G to T substitution at nucleotide position 694, causing the aspartic acid (D) at amino acid position 232 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
