The c.248A>G (p.Y83C) alteration is located in exon 3 (coding exon 3) of the LDHAL6A gene. This alteration results from a A to G substitution at nucleotide position 248, causing the tyrosine (Y) at amino acid position 83 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
