Genes affected

DLX5 (HGNC:2918): (distal-less homeobox 5) This gene encodes a member of a homeobox transcription factor gene family similiar to the Drosophila distal-less gene. The encoded protein may play a role in bone development and fracture healing. Mutation in this gene, which is located in a tail-to-tail configuration with another member of the family on the long arm of chromosome 7, may be associated with split-hand/split-foot malformation.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 7-97024509-C-A is Pathogenic according to our data. Variant chr7-97024509-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 156469.Status of the report is no_assertion_criteria_provided, 0 stars.
