Oct 18, 2021

The c.10G>A (p.D4N) alteration is located in exon 1 (coding exon 1) of the C2orf49 gene. This alteration results from a G to A substitution at nucleotide position 10, causing the aspartic acid (D) at amino acid position 4 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
