Genes affected

SFT2D3 (HGNC:28767): (SFT2 domain containing 3) Predicted to be involved in protein transport and vesicle-mediated transport. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

SFT2D3 links:

WDR33 (HGNC:25651): (WD repeat domain 33) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. This gene is highly expressed in testis and the protein is localized to the nucleus. This gene may play important roles in the mechanisms of cytodifferentiation and/or DNA recombination. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.184G>A (p.A62T) alteration is located in exon 1 (coding exon 1) of the SFT2D3 gene. This alteration results from a G to A substitution at nucleotide position 184, causing the alanine (A) at amino acid position 62 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
