The c.143A>G (p.Q48R) alteration is located in exon 2 (coding exon 1) of the SLC25A44 gene. This alteration results from a A to G substitution at nucleotide position 143, causing the glutamine (Q) at amino acid position 48 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
