The c.133C>A (p.Q45K) alteration is located in exon 3 (coding exon 3) of the DMRTC1 gene. This alteration results from a C to A substitution at nucleotide position 133, causing the glutamine (Q) at amino acid position 45 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
