The c.428A>G (p.Y143C) alteration is located in exon 4 (coding exon 4) of the HRASLS5 gene. This alteration results from a A to G substitution at nucleotide position 428, causing the tyrosine (Y) at amino acid position 143 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
