Genes affected

PRKX (HGNC:9441): (protein kinase cAMP-dependent X-linked catalytic subunit) This gene encodes a serine threonine protein kinase that has similarity to the catalytic subunit of cyclic AMP dependent protein kinases. The encoded protein is developmentally regulated and may be involved in renal epithelial morphogenesis. This protein may also be involved in macrophage and granulocyte maturation. Abnormal recombination between this gene and a related pseudogene on chromosome Y is a frequent cause of sex reversal disorder in XX males and XY females. Pseudogenes of this gene are found on chromosomes X, 15 and Y. [provided by RefSeq, Feb 2010]

Ambry Genetics

Feb 28, 2023

The c.901C>T (p.R301W) alteration is located in exon 7 (coding exon 7) of the PRKX gene. This alteration results from a C to T substitution at nucleotide position 901, causing the arginine (R) at amino acid position 301 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
