not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.548G>A (p.R183Q) alteration is located in exon 6 (coding exon 5) of the FNDC3B gene. This alteration results from a G to A substitution at nucleotide position 548, causing the arginine (R) at amino acid position 183 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
