The c.1562G>A (p.R521Q) alteration is located in exon 16 (coding exon 16) of the TTC39B gene. This alteration results from a G to A substitution at nucleotide position 1562, causing the arginine (R) at amino acid position 521 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
