The c.4291C>T (p.H1431Y) alteration is located in exon 22 (coding exon 21) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 4291, causing the histidine (H) at amino acid position 1431 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
