Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM2BP4_StrongBP6_ModerateBP7BS1

The NM_014319.5(LEMD3):c.15A>G(p.Ala5=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000279 in 1,435,816 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. A5A) has been classified as Likely benign.

Genes affected

LEMD3 (HGNC:28887): (LEM domain containing 3) This locus encodes a LEM domain-containing protein. The encoded protein functions to antagonize transforming growth factor-beta signaling at the inner nuclear membrane. Two transcript variants encoding different isoforms have been found for this gene. Mutations in this gene have been associated with osteopoikilosis, Buschke-Ollendorff syndrome and melorheostosis.[provided by RefSeq, Nov 2009]
