Dec 18, 2023

The c.285C>G (p.D95E) alteration is located in exon 3 (coding exon 2) of the FAM150B gene. This alteration results from a C to G substitution at nucleotide position 285, causing the aspartic acid (D) at amino acid position 95 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
