Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.121C>T (p.P41S) alteration is located in exon 1 (coding exon 1) of the FAM47C gene. This alteration results from a C to T substitution at nucleotide position 121, causing the proline (P) at amino acid position 41 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
