Genes affected
SLC16A2 (HGNC:10923): (solute carrier family 16 member 2) This gene encodes an integral membrane protein that functions as a transporter of thyroid hormone. The encoded protein facilitates the cellular importation of thyroxine (T4), triiodothyronine (T3), reverse triiodothyronine (rT3) and diidothyronine (T2). This gene is expressed in many tissues and likely plays an important role in the development of the central nervous system. Loss of function mutations in this gene are associated with psychomotor retardation in males while females exhibit no neurological defects and more moderate thyroid-deficient phenotypes. This gene is subject to X-chromosome inactivation. Mutations in this gene are the cause of Allan-Herndon-Dudley syndrome. [provided by RefSeq, Mar 2012]

Spastic paraplegia Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Nov 18, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with SLC16A2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Leu3Profs*26) in the SLC16A2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC16A2 are known to be pathogenic (PMID: 20083155, 25527620). - |
