The c.388G>T (p.A130S) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a G to T substitution at nucleotide position 388, causing the alanine (A) at amino acid position 130 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
