Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.530C>T (p.A177V) alteration is located in exon 5 (coding exon 5) of the TECTB gene. This alteration results from a C to T substitution at nucleotide position 530, causing the alanine (A) at amino acid position 177 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
