Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.251G>A (p.R84Q) alteration is located in exon 5 (coding exon 4) of the NDUFA4L2 gene. This alteration results from a G to A substitution at nucleotide position 251, causing the arginine (R) at amino acid position 84 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
