The c.25G>T (p.A9S) alteration is located in exon 2 (coding exon 1) of the D4S234E gene. This alteration results from a G to T substitution at nucleotide position 25, causing the alanine (A) at amino acid position 9 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
