Genes affected
LEMD2 (HGNC:21244): (LEM domain nuclear envelope protein 2) This gene encodes a LEM domain-containing transmembrane protein of the inner nuclear membrane. The protein is involved in nuclear structure organization and plays a role in cell signaling and differentiation. Mutations in this gene result in Cataract 46, juvenile-onset. Multiple transcript variants have been found for this gene. [provided by RefSeq, Feb 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.1199G>A (p.R400Q) alteration is located in exon 7 (coding exon 7) of the LEMD2 gene. This alteration results from a G to A substitution at nucleotide position 1199, causing the arginine (R) at amino acid position 400 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
