The c.758C>A (p.A253D) alteration is located in exon 6 (coding exon 6) of the HRASLS5 gene. This alteration results from a C to A substitution at nucleotide position 758, causing the alanine (A) at amino acid position 253 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
