Ambry Genetics

Jan 09, 2024

The c.148C>G (p.P50A) alteration is located in exon 5 (coding exon 3) of the TMEM150B gene. This alteration results from a C to G substitution at nucleotide position 148, causing the proline (P) at amino acid position 50 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
