Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_020389.3(TRPC7):c.2209G>A(p.Ala737Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000138 in 1,452,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A737V) has been classified as Uncertain significance.

Collection Method:clinical testing

The c.2209G>A (p.A737T) alteration is located in exon 9 (coding exon 9) of the TRPC7 gene. This alteration results from a G to A substitution at nucleotide position 2209, causing the alanine (A) at amino acid position 737 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
