The c.442A>G (p.S148G) alteration is located in exon 4 (coding exon 1) of the C21orf62 gene. This alteration results from a A to G substitution at nucleotide position 442, causing the serine (S) at amino acid position 148 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
