Variant chrX-3615865-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP3_ModerateBS2

The NM_005044.5(PRKX):c.901C>T(p.Arg301Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000497 in 1,206,164 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 17 hemizygotes in GnomAD. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R301Q) has been classified as Uncertain significance.

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. -
