Jun 28, 2022

The c.835C>G (p.P279A) alteration is located in exon 7 (coding exon 5) of the FAM234A gene. This alteration results from a C to G substitution at nucleotide position 835, causing the proline (P) at amino acid position 279 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
