Dec 14, 2022

The c.608C>T (p.T203M) alteration is located in exon 6 (coding exon 5) of the SERPINB5 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the threonine (T) at amino acid position 203 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
