Genes affected
ITGBL1 (HGNC:6164): (integrin subunit beta like 1) This gene encodes a beta integrin-related protein that is a member of the EGF-like protein family. The encoded protein contains integrin-like cysteine-rich repeats. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.1097G>A (p.R366H) alteration is located in exon 8 (coding exon 8) of the ITGBL1 gene. This alteration results from a G to A substitution at nucleotide position 1097, causing the arginine (R) at amino acid position 366 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
