The c.449G>A (p.R150H) alteration is located in exon 4 (coding exon 4) of the FAM162B gene. This alteration results from a G to A substitution at nucleotide position 449, causing the arginine (R) at amino acid position 150 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
