Genes affected

RIPPLY1 (HGNC:25117): (ripply transcriptional repressor 1) This gene encodes a protein similar to a zebrafish protein which acts as a transcriptional repressor in and is required for somite segmentation in zebrafish embryos (PMID: 16326386). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

RIPPLY1 links:

CLDN2 (HGNC:2041): (claudin 2) This gene product belongs to the claudin protein family whose members have been identified as major integral membrane proteins localized exclusively at tight junctions. Claudins are expressed in an organ-specific manner and regulate tissue-specific physiologic properties of tight junctions. This protein is expressed in the intestine. Alternatively spliced transcript variants with different 5' untranslated region have been found for this gene.[provided by RefSeq, Jan 2010]

CLDN2 links:

MORC4 (HGNC:23485): (MORC family CW-type zinc finger 4) In human, the four current members of the microrchidia (morc) gene family share an N-terminal ATPase-like ATP-binding region and a CW four-cysteine zinc-finger motif. The protein encoded by this gene also has a nuclear matrix binding domain and a two-stranded coiled-coil motif near its C-terminus. This gene is widely expressed at low levels in normal tissues and has elevated expression in placenta and testis. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jan 2010]

Ambry Genetics

Sep 15, 2021

The c.362A>G (p.N121S) alteration is located in exon 4 (coding exon 4) of the RIPPLY1 gene. This alteration results from a A to G substitution at nucleotide position 362, causing the asparagine (N) at amino acid position 121 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
