The c.1012G>C (p.A338P) alteration is located in exon 4 (coding exon 4) of the FAM83E gene. This alteration results from a G to C substitution at nucleotide position 1012, causing the alanine (A) at amino acid position 338 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
