The c.4272C>G (p.D1424E) alteration is located in exon 14 (coding exon 14) of the SOGA1 gene. This alteration results from a C to G substitution at nucleotide position 4272, causing the aspartic acid (D) at amino acid position 1424 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
