The c.842C>G (p.T281S) alteration is located in exon 4 (coding exon 3) of the MANSC1 gene. This alteration results from a C to G substitution at nucleotide position 842, causing the threonine (T) at amino acid position 281 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
