Genes affected

LAMA5 (HGNC:6485): (laminin subunit alpha 5) This gene encodes one of the vertebrate laminin alpha chains. Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins are composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively) and they form a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. The protein encoded by this gene is the alpha-5 subunit of of laminin-10 (laminin-511), laminin-11 (laminin-521) and laminin-15 (laminin-523). [provided by RefSeq, Jun 2013]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.006543368).

BP6

Variant 20-62310186-C-T is Benign according to our data. Variant chr20-62310186-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 438605.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00384 (585/152314) while in subpopulation NFE AF = 0.00616 (419/68010). AF 95% confidence interval is 0.00567. There are 4 homozygotes in GnomAd4. There are 260 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 4 AR,AD gene
