The c.5722T>C (p.Y1908H) alteration is located in exon 46 (coding exon 43) of the FRYL gene. This alteration results from a T to C substitution at nucleotide position 5722, causing the tyrosine (Y) at amino acid position 1908 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
