The c.3127C>T (p.P1043S) alteration is located in exon 17 (coding exon 17) of the HELQ gene. This alteration results from a C to T substitution at nucleotide position 3127, causing the proline (P) at amino acid position 1043 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
