The c.77T>G (p.V26G) alteration is located in exon 1 (coding exon 1) of the ANKRD33 gene. This alteration results from a T to G substitution at nucleotide position 77, causing the valine (V) at amino acid position 26 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
