Collection Method: clinical testing

The c.449C>T (p.T150M) alteration is located in exon 5 (coding exon 3) of the FAM114A1 gene. This alteration results from a C to T substitution at nucleotide position 449, causing the threonine (T) at amino acid position 150 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
