The c.170T>C (p.V57A) alteration is located in exon 4 (coding exon 3) of the YPEL2 gene. This alteration results from a T to C substitution at nucleotide position 170, causing the valine (V) at amino acid position 57 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
