The c.920C>G (p.T307S) alteration is located in exon 9 (coding exon 8) of the MYRIP gene. This alteration results from a C to G substitution at nucleotide position 920, causing the threonine (T) at amino acid position 307 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
