The c.539C>T (p.A180V) alteration is located in exon 4 (coding exon 4) of the SOBP gene. This alteration results from a C to T substitution at nucleotide position 539, causing the alanine (A) at amino acid position 180 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
