The c.176G>A (p.R59H) alteration is located in exon 1 (coding exon 1) of the FAM47B gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
