Genes affected

DENND6A (HGNC:26635): (DENN domain containing 6A) Enables guanyl-nucleotide exchange factor activity. Involved in positive regulation of cell-cell adhesion mediated by cadherin. Located in recycling endosome. [provided by Alliance of Genome Resources, Apr 2022]

DENND6A links:

PDE12 (HGNC:25386): (phosphodiesterase 12) Enables 3'-5'-exoribonuclease activity. Involved in several processes, including RNA metabolic process; cellular response to cytokine stimulus; and regulation of mitochondrial mRNA stability. Located in mitochondrial matrix.

Ambry Genetics

Dec 03, 2024

The c.1609C>A (p.L537I) alteration is located in exon 18 (coding exon 18) of the DENND6A gene. This alteration results from a C to A substitution at nucleotide position 1609, causing the leucine (L) at amino acid position 537 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
