The c.236A>G (p.Y79C) alteration is located in exon 2 (coding exon 2) of the MICU2 gene. This alteration results from a A to G substitution at nucleotide position 236, causing the tyrosine (Y) at amino acid position 79 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
