The c.1199G>A (p.R400H) alteration is located in exon 5 (coding exon 5) of the NCEH1 gene. This alteration results from a G to A substitution at nucleotide position 1199, causing the arginine (R) at amino acid position 400 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
