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]

The c.1055A>G (p.K352R) alteration is located in exon 6 (coding exon 6) of the LEMD2 gene. This alteration results from a A to G substitution at nucleotide position 1055, causing the lysine (K) at amino acid position 352 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
