Genes affected

ITGB8 (HGNC:6163): (integrin subunit beta 8) This gene is a member of the integrin beta chain family and encodes a single-pass type I membrane protein with a VWFA domain and four cysteine-rich repeats. This protein noncovalently binds to an alpha subunit to form a heterodimeric integrin complex. In general, integrin complexes mediate cell-cell and cell-extracellular matrix interactions and this complex plays a role in human airway epithelial proliferation. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]

The c.1091G>A (p.G364D) alteration is located in exon 8 (coding exon 8) of the ITGB8 gene. This alteration results from a G to A substitution at nucleotide position 1091, causing the glycine (G) at amino acid position 364 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
