Genes affected
ITGA7 (HGNC:6143): (integrin subunit alpha 7) The protein encoded by this gene belongs to the integrin alpha chain family. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. They mediate a wide spectrum of cell-cell and cell-matrix interactions, and thus play a role in cell migration, morphologic development, differentiation, and metastasis. This protein functions as a receptor for the basement membrane protein laminin-1. It is mainly expressed in skeletal and cardiac muscles and may be involved in differentiation and migration processes during myogenesis. Defects in this gene are associated with congenital myopathy. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Feb 2009]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.2000998).
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000404 (59/1461526) while in subpopulation MID AF = 0.0014 (8/5714). AF 95% confidence interval is 0.000696. There are 1 homozygotes in GnomAdExome4. There are 38 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.
