Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.16G>C (p.D6H) alteration is located in exon 2 (coding exon 1) of the ANKZF1 gene. This alteration results from a G to C substitution at nucleotide position 16, causing the aspartic acid (D) at amino acid position 6 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
