Genes affected

TMCO3 (HGNC:20329): (transmembrane and coiled-coil domains 3) This gene encodes a member of the monovalent cation:proton antiporter 2 (CPA2) family of transporter proteins. Members of this family typically couple the export of monovalent cations, such as potassium or sodium, to the import of protons across cellular membranes. Mutations in this gene have been identified in patients with a rare inherited vision defect, cornea guttata with anterior polar cataract. [provided by RefSeq, Mar 2017]

Dec 19, 2022

The c.149T>C (p.V50A) alteration is located in exon 2 (coding exon 1) of the TMCO3 gene. This alteration results from a T to C substitution at nucleotide position 149, causing the valine (V) at amino acid position 50 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
