The c.2038T>C (p.Y680H) alteration is located in exon 20 (coding exon 20) of the ANKRD44 gene. This alteration results from a T to C substitution at nucleotide position 2038, causing the tyrosine (Y) at amino acid position 680 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
