Genes affected

MARCHF6 (HGNC:30550): (membrane associated ring-CH-type finger 6) This gene encodes a member of a family of membrane-associated E3 ubiquitin ligases containing RING-CH-type zinc finger motifs. Ubiquitination of type II deiodinase by the encoded protein is an important regulatory step in thyroid hormone signalling. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

The c.452C>T (p.T151M) alteration is located in exon 6 (coding exon 6) of the MARCH6 gene. This alteration results from a C to T substitution at nucleotide position 452, causing the threonine (T) at amino acid position 151 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
