Genes affected

NIPAL4 (HGNC:28018): (NIPA like domain containing 4) This gene likely encodes a membrane receptor. Mutations in this gene have been associated with autosomal recessive congenital ichthyosis. [provided by RefSeq, Feb 2010]

NIPAL4 links:

ADAM19 (HGNC:197): (ADAM metallopeptidase domain 19) This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. This member is a type I transmembrane protein and serves as a marker for dendritic cell differentiation. It has been demonstrated to be an active metalloproteinase, which may be involved in normal physiological processes such as cell migration, cell adhesion, cell-cell and cell-matrix interactions, and signal transduction. It is proposed to play a role in pathological processes, such as cancer, inflammatory diseases, renal diseases, and Alzheimer's disease. [provided by RefSeq, May 2013]

Ambry Genetics

Dec 19, 2023

The c.295G>A (p.V99M) alteration is located in exon 2 (coding exon 2) of the NIPAL4 gene. This alteration results from a G to A substitution at nucleotide position 295, causing the valine (V) at amino acid position 99 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
