The c.5888C>T (p.A1963V) alteration is located in exon 41 (coding exon 40) of the HEATR1 gene. This alteration results from a C to T substitution at nucleotide position 5888, causing the alanine (A) at amino acid position 1963 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
