Genes affected
CTNNA1 (HGNC:2509): (catenin alpha 1) This gene encodes a member of the catenin family of proteins that play an important role in cell adhesion process by connecting cadherins located on the plasma membrane to the actin filaments inside the cell. The encoded mechanosensing protein contains three vinculin homology domains and undergoes conformational changes in response to cytoskeletal tension, resulting in the reconfiguration of cadherin-actin filament connections. Certain mutations in this gene cause butterfly-shaped pigment dystrophy. [provided by RefSeq, May 2016]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.7).
BP6
Variant 5-138917757-C-T is Benign according to our data. Variant chr5-138917757-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 415354.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.308 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0105 (1602/152294) while in subpopulation AFR AF= 0.0366 (1523/41568). AF 95% confidence interval is 0.0351. There are 26 homozygotes in gnomad4. There are 751 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High AC in GnomAd4 at 1602 AD gene.
