Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_001042463.3(TMEM80):c.157C>T(p.Arg53Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000285 in 1,613,952 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. R53H) has been classified as Likely benign.

Genes affected

TMEM80 (HGNC:27453): (transmembrane protein 80) Predicted to be involved in non-motile cilium assembly. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in ciliary transition zone. [provided by Alliance of Genome Resources, Apr 2022]

TMEM80 links:

DEAF1 (HGNC:14677): (DEAF1 transcription factor) This gene encodes a zinc finger domain-containing protein that functions as a regulator of transcription. The encoded proteins binds to its own promoter as well as to that of several target genes. Activity of this protein is important in the regulation of embryonic development. Mutations in this gene have been found in individuals with autosomal dominant cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

DEAF1 links:

EPS8L2 (HGNC:21296): (EPS8 signaling adaptor L2) This gene encodes a member of the EPS8 gene family. The encoded protein, like other members of the family, is thought to link growth factor stimulation to actin organization, generating functional redundancy in the pathways that regulate actin cytoskeletal remodeling. [provided by RefSeq, Dec 2008]

Collection Method:clinical testing

The c.232C>T (p.R78C) alteration is located in exon 4 (coding exon 4) of the TMEM80 gene. This alteration results from a C to T substitution at nucleotide position 232, causing the arginine (R) at amino acid position 78 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
