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 GeneticsOct 25, 2023The c.991G>A (p.E331K) alteration is located in exon 2 (coding exon 2) of the LMOD1 gene. This alteration results from a G to A substitution at nucleotide position 991, causing the glutamic acid (E) at amino acid position 331 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
