Sep 17, 2021

The c.2104C>T (p.H702Y) alteration is located in exon 13 (coding exon 12) of the AKNAD1 gene. This alteration results from a C to T substitution at nucleotide position 2104, causing the histidine (H) at amino acid position 702 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
