Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.2188A>C (p.I730L) alteration is located in exon 9 (coding exon 9) of the TRPC7 gene. This alteration results from a A to C substitution at nucleotide position 2188, causing the isoleucine (I) at amino acid position 730 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
