Ambry Genetics

Nov 24, 2024

The c.611C>T (p.S204L) alteration is located in exon 7 (coding exon 7) of the TMEM120A gene. This alteration results from a C to T substitution at nucleotide position 611, causing the serine (S) at amino acid position 204 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
