Collection Method: clinical testing

The c.490A>T (p.I164F) alteration is located in exon 4 (coding exon 4) of the OSCP1 gene. This alteration results from a A to T substitution at nucleotide position 490, causing the isoleucine (I) at amino acid position 164 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
