The c.515A>T (p.E172V) alteration is located in exon 5 (coding exon 5) of the IQCJ-SCHIP1 gene. This alteration results from a A to T substitution at nucleotide position 515, causing the glutamic acid (E) at amino acid position 172 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
