The c.886G>T (p.G296C) alteration is located in exon 8 (coding exon 7) of the SAMD14 gene. This alteration results from a G to T substitution at nucleotide position 886, causing the glycine (G) at amino acid position 296 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
