The c.264T>A (p.D88E) alteration is located in exon 2 (coding exon 2) of the SPESP1 gene. This alteration results from a T to A substitution at nucleotide position 264, causing the aspartic acid (D) at amino acid position 88 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
