Ambry Genetics

Nov 15, 2021

The c.227T>C (p.M76T) alteration is located in exon 5 (coding exon 4) of the TMEM14C gene. This alteration results from a T to C substitution at nucleotide position 227, causing the methionine (M) at amino acid position 76 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
