The c.104C>T (p.A35V) alteration is located in exon 2 (coding exon 2) of the MSTO1 gene. This alteration results from a C to T substitution at nucleotide position 104, causing the alanine (A) at amino acid position 35 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
