The c.261C>A (p.D87E) alteration is located in exon 3 (coding exon 3) of the DPYSL4 gene. This alteration results from a C to A substitution at nucleotide position 261, causing the aspartic acid (D) at amino acid position 87 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
