The c.1777G>A (p.A593T) alteration is located in exon 16 (coding exon 16) of the NOC3L gene. This alteration results from a G to A substitution at nucleotide position 1777, causing the alanine (A) at amino acid position 593 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
