The c.541G>T (p.A181S) alteration is located in exon 6 (coding exon 6) of the PDXDC1 gene. This alteration results from a G to T substitution at nucleotide position 541, causing the alanine (A) at amino acid position 181 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
