Collection Method: clinical testing

The c.895A>G (p.I299V) alteration is located in exon 9 (coding exon 8) of the MYRIP gene. This alteration results from a A to G substitution at nucleotide position 895, causing the isoleucine (I) at amino acid position 299 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
