The c.2035C>T (p.L679F) alteration is located in exon 22 (coding exon 22) of the SDAD1 gene. This alteration results from a C to T substitution at nucleotide position 2035, causing the leucine (L) at amino acid position 679 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
