Genes affected
TMEM127 (HGNC:26038): (transmembrane protein 127) This gene encodes a transmembrane protein with four predicted transmembrane domains. The protein is associated with a subpopulation of vesicular organelles corresponding to early endosomal structures, with the Golgi, and with lysosomes, and may participate in protein trafficking between these structures. Mutations in this gene and several other genes cause pheochromocytomas. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Aug 2022]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, Dann, Eigen, phyloP100way_vertebrate, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationAssessor, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.0155994).
BP6
Variant 2-96253953-G-A is Benign according to our data. Variant chr2-96253953-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 486539.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1, Benign=3}.
BS2
High AC in GnomAd4 at 112 AD gene.

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
