The c.5794G>T (p.V1932F) alteration is located in exon 35 (coding exon 34) of the HEATR5B gene. This alteration results from a G to T substitution at nucleotide position 5794, causing the valine (V) at amino acid position 1932 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
