Genes affected

LAD1 (HGNC:6472): (ladinin 1) The protein encoded by this gene may be an anchoring filament that is a component of basement membranes. It may contribute to the stability of the association of the epithelial layers with the underlying mesenchyme. [provided by RefSeq, Jul 2008]

Ambry Genetics

Aug 12, 2021

The c.28G>A (p.A10T) alteration is located in exon 1 (coding exon 1) of the LAD1 gene. This alteration results from a G to A substitution at nucleotide position 28, causing the alanine (A) at amino acid position 10 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
