Sep 16, 2021

The c.1801C>T (p.R601C) alteration is located in exon 20 (coding exon 20) of the SDAD1 gene. This alteration results from a C to T substitution at nucleotide position 1801, causing the arginine (R) at amino acid position 601 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
