The c.416G>A (p.S139N) alteration is located in exon 5 (coding exon 1) of the ANKRD34B gene. This alteration results from a G to A substitution at nucleotide position 416, causing the serine (S) at amino acid position 139 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
