Genes affected

TMCO1 (HGNC:18188): (transmembrane and coiled-coil domains 1) This locus encodes a transmembrane protein. Mutations at this locus have been associated with craniofacial dysmorphism, skeletal anomalies, and cognitive disability. Mutations at this locus have also been associated with open angle glaucoma blindness. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

Collection Method: clinical testing

The c.340G>T (p.V114L) alteration is located in exon 6 (coding exon 6) of the TMCO1 gene. This alteration results from a G to T substitution at nucleotide position 340, causing the valine (V) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
