The c.217G>T (p.D73Y) alteration is located in exon 3 (coding exon 2) of the HRASLS gene. This alteration results from a G to T substitution at nucleotide position 217, causing the aspartic acid (D) at amino acid position 73 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
