The c.334C>A (p.R112S) alteration is located in exon 1 (coding exon 1) of the MICU3 gene. This alteration results from a C to A substitution at nucleotide position 334, causing the arginine (R) at amino acid position 112 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
