Genes affected
TMEM79 (HGNC:28196): (transmembrane protein 79) Enables identical protein binding activity. Predicted to be involved in several processes, including epithelial cell maturation; establishment of skin barrier; and positive regulation of epidermis development. Predicted to act upstream of or within cornification; cuticle development; and hair follicle morphogenesis. Predicted to be located in cytoplasm. Predicted to be active in lysosomal membrane and trans-Golgi network membrane. [provided by Alliance of Genome Resources, Apr 2022]
SMG5 (HGNC:24644): (SMG5 nonsense mediated mRNA decay factor) SMG5 is involved in nonsense-mediated mRNA decay (Ohnishi et al., 2003 [PubMed 14636577]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2022The c.535G>A (p.V179M) alteration is located in exon 2 (coding exon 1) of the TMEM79 gene. This alteration results from a G to A substitution at nucleotide position 535, causing the valine (V) at amino acid position 179 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
