The c.575T>G (p.L192R) alteration is located in exon 4 (coding exon 4) of the VWA5B2 gene. This alteration results from a T to G substitution at nucleotide position 575, causing the leucine (L) at amino acid position 192 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
