The c.74C>T (p.S25L) alteration is located in exon 2 (coding exon 1) of the TMOD3 gene. This alteration results from a C to T substitution at nucleotide position 74, causing the serine (S) at amino acid position 25 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
