The c.575A>C (p.D192A) alteration is located in exon 8 (coding exon 6) of the STXBP4 gene. This alteration results from a A to C substitution at nucleotide position 575, causing the aspartic acid (D) at amino acid position 192 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
