The c.827A>T (p.Q276L) alteration is located in exon 8 (coding exon 8) of the RAP1GDS1 gene. This alteration results from a A to T substitution at nucleotide position 827, causing the glutamine (Q) at amino acid position 276 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
