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)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.406C>T (p.H136Y) alteration is located in exon 3 (coding exon 3) of the SHROOM3 gene. This alteration results from a C to T substitution at nucleotide position 406, causing the histidine (H) at amino acid position 136 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
