Collection Method: clinical testing

The c.542C>T (p.T181M) alteration is located in exon 4 (coding exon 4) of the ESYT3 gene. This alteration results from a C to T substitution at nucleotide position 542, causing the threonine (T) at amino acid position 181 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
