The c.233A>G (p.Y78C) alteration is located in exon 4 (coding exon 4) of the CLEC17A gene. This alteration results from a A to G substitution at nucleotide position 233, causing the tyrosine (Y) at amino acid position 78 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
