Genes affected
CTDNEP1 (HGNC:19085): (CTD nuclear envelope phosphatase 1) Enables protein serine/threonine phosphatase activity. Involved in several processes, including positive regulation of triglyceride biosynthetic process; protein dephosphorylation; and protein localization to nucleus. Located in endoplasmic reticulum membrane; lipid droplet; and nuclear membrane. Part of Nem1-Spo7 phosphatase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.79C>T (p.L27F) alteration is located in exon 2 (coding exon 1) of the CTDNEP1 gene. This alteration results from a C to T substitution at nucleotide position 79, causing the leucine (L) at amino acid position 27 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
