The c.548C>T (p.A183V) alteration is located in exon 4 (coding exon 4) of the THSD4 gene. This alteration results from a C to T substitution at nucleotide position 548, causing the alanine (A) at amino acid position 183 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
