Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_032780.4(TMEM25):c.499G>A(p.Asp167Asn) variant causes a missense change. The variant allele was found at a frequency of 0.000139 in 1,614,224 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D167H) has been classified as Uncertain significance.
TMEM25 (HGNC:25890): (transmembrane protein 25) Predicted to be involved in negative regulation of excitatory postsynaptic potential and regulation of protein stability. Predicted to be located in late endosome and lysosome. [provided by Alliance of Genome Resources, Apr 2022]
