Genes affected

FHOD1 (HGNC:17905): (formin homology 2 domain containing 1) This gene encodes a protein which is a member of the formin/diaphanous family of proteins. The gene is ubiquitously expressed but is found in abundance in the spleen. The encoded protein has sequence homology to diaphanous and formin proteins within the Formin Homology (FH)1 and FH2 domains. It also contains a coiled-coil domain, a collagen-like domain, two nuclear localization signals, and several potential PKC and PKA phosphorylation sites. It is a predominantly cytoplasmic protein and is expressed in a variety of human cell lines. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

SLC9A5 (HGNC:):

SLC9A5 (HGNC:11078): (solute carrier family 9 member A5) Predicted to enable potassium:proton antiporter activity and sodium:proton antiporter activity. Predicted to be involved in potassium ion transmembrane transport; regulation of intracellular pH; and sodium ion import across plasma membrane. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Implicated in end stage renal disease. [provided by Alliance of Genome Resources, Apr 2022]

The c.107A>G (p.E36G) alteration is located in exon 1 (coding exon 1) of the FHOD1 gene. This alteration results from a A to G substitution at nucleotide position 107, causing the glutamic acid (E) at amino acid position 36 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
