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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 05, 2024 | The c.37T>C (p.F13L) alteration is located in exon 1 (coding exon 1) of the ITGB8 gene. This alteration results from a T to C substitution at nucleotide position 37, causing the phenylalanine (F) at amino acid position 13 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
