The c.158T>C (p.L53P) alteration is located in exon 4 (coding exon 2) of the FAM229B gene. This alteration results from a T to C substitution at nucleotide position 158, causing the leucine (L) at amino acid position 53 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
