Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.260C>T (p.P87L) alteration is located in exon 5 (coding exon 2) of the FAM160A1 gene. This alteration results from a C to T substitution at nucleotide position 260, causing the proline (P) at amino acid position 87 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
