Genes affected

SH3PXD2B (HGNC:29242): (SH3 and PX domains 2B) This gene encodes an adapter protein that is characterized by a PX domain and four Src homology 3 domains. The encoded protein is required for podosome formation and is involved in cell adhesion and migration of numerous cell types. Mutations in this gene are the cause of Frank-ter Haar syndrome (FTHS), and also Borrone Dermato-Cardio-Skeletal (BDCS) syndrome. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Uncertain significance, criteria provided, single submitter	clinical testing	Eurofins Ntd Llc (ga)	Oct 07, 2016	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 31, 2021	This sequence change replaces arginine with glutamine at codon 698 of the SH3PXD2B protein (p.Arg698Gln). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs144659619, ExAC 0.2%). This variant has not been reported in the literature in individuals affected with SH3PXD2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 497282). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
