The c.335A>G (p.Y112C) alteration is located in exon 4 (coding exon 4) of the HACD4 gene. This alteration results from a A to G substitution at nucleotide position 335, causing the tyrosine (Y) at amino acid position 112 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
