Genes affected
LMOD1 (HGNC:6647): (leiomodin 1) The leiomodin 1 protein has a putative membrane-spanning region and 2 types of tandemly repeated blocks. The transcript is expressed in all tissues tested, with the highest levels in thyroid, eye muscle, skeletal muscle, and ovary. Increased expression of leiomodin 1 may be linked to Graves' disease and thyroid-associated ophthalmopathy. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.997A>G (p.T333A) alteration is located in exon 2 (coding exon 2) of the LMOD1 gene. This alteration results from a A to G substitution at nucleotide position 997, causing the threonine (T) at amino acid position 333 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
