Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_001284401.2(TAMM41):​c.398G>T​(p.Arg133Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,459,782 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R133Q) has been classified as Uncertain significance.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 05, 2021The c.398G>T (p.R133L) alteration is located in exon 3 (coding exon 3) of the TAMM41 gene. This alteration results from a G to T substitution at nucleotide position 398, causing the arginine (R) at amino acid position 133 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
