Genes affected
SHROOM3 (HGNC:30422): (shroom family member 3) This gene encodes a PDZ-domain-containing protein that belongs to a family of Shroom-related proteins. This protein may be involved in regulating cell shape in certain tissues. A similar protein in mice is required for proper neurulation. [provided by RefSeq, Jan 2011]
SHROOM3-AS1 (HGNC:41265): (SHROOM3 antisense RNA 1)

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.822C>A (p.H274Q) alteration is located in exon 5 (coding exon 5) of the SHROOM3 gene. This alteration results from a C to A substitution at nucleotide position 822, causing the histidine (H) at amino acid position 274 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
