The c.710A>G (p.Y237C) alteration is located in exon 7 (coding exon 7) of the TGM4 gene. This alteration results from a A to G substitution at nucleotide position 710, causing the tyrosine (Y) at amino acid position 237 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
