The c.1054A>G (p.I352V) alteration is located in exon 10 (coding exon 10) of the OSCP1 gene. This alteration results from a A to G substitution at nucleotide position 1054, causing the isoleucine (I) at amino acid position 352 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
