Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.131T>C (p.V44A) alteration is located in exon 2 (coding exon 2) of the ALKBH6 gene. This alteration results from a T to C substitution at nucleotide position 131, causing the valine (V) at amino acid position 44 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
