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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.159C>A (p.D53E) alteration is located in exon 2 (coding exon 2) of the LAD1 gene. This alteration results from a C to A substitution at nucleotide position 159, causing the aspartic acid (D) at amino acid position 53 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
