Genes affected

DBNL (HGNC:2696): (drebrin like) Enables cadherin binding activity. Predicted to be involved in several processes, including Rac protein signal transduction; nervous system development; and podosome assembly. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

PGAM2 (HGNC:8889): (phosphoglycerate mutase 2) Phosphoglycerate mutase (PGAM) catalyzes the reversible reaction of 3-phosphoglycerate (3-PGA) to 2-phosphoglycerate (2-PGA) in the glycolytic pathway. The PGAM is a dimeric enzyme containing, in different tissues, different proportions of a slow-migrating muscle (MM) isozyme, a fast-migrating brain (BB) isozyme, and a hybrid form (MB). This gene encodes muscle-specific PGAM subunit. Mutations in this gene cause muscle phosphoglycerate mutase eficiency, also known as glycogen storage disease X. [provided by RefSeq, Sep 2009]

PGAM2 Gene-Disease associations (from GenCC):

• glycogen storage disease due to phosphoglycerate mutase deficiency

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 7-44062933-A-G is Benign according to our data. Variant chr7-44062933-A-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 360271.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High Homozygotes in GnomAdExome4 at 8 AR gene
