The c.622T>C (p.Y208H) alteration is located in exon 5 (coding exon 3) of the NXPE1 gene. This alteration results from a T to C substitution at nucleotide position 622, causing the tyrosine (Y) at amino acid position 208 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
