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.1502C>T (p.S501L) alteration is located in exon 9 (coding exon 9) of the LEMD2 gene. This alteration results from a C to T substitution at nucleotide position 1502, causing the serine (S) at amino acid position 501 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
