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]

The c.399C>G (p.D133E) alteration is located in exon 2 (coding exon 1) of the TMEM79 gene. This alteration results from a C to G substitution at nucleotide position 399, causing the aspartic acid (D) at amino acid position 133 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
