The c.4283C>T (p.S1428L) alteration is located in exon 14 (coding exon 14) of the SOGA1 gene. This alteration results from a C to T substitution at nucleotide position 4283, causing the serine (S) at amino acid position 1428 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
