The c.6152A>G (p.Q2051R) alteration is located in exon 43 (coding exon 42) of the HEATR1 gene. This alteration results from a A to G substitution at nucleotide position 6152, causing the glutamine (Q) at amino acid position 2051 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
