The c.3488A>G (p.K1163R) alteration is located in exon 5 (coding exon 4) of the FAM83H gene. This alteration results from a A to G substitution at nucleotide position 3488, causing the lysine (K) at amino acid position 1163 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
