Feb 12, 2024

The c.316C>T (p.P106S) alteration is located in exon 2 (coding exon 2) of the FMR1NB gene. This alteration results from a C to T substitution at nucleotide position 316, causing the proline (P) at amino acid position 106 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
