Genes affected
DYDC2 (HGNC:23468): (DPY30 domain containing 2) This gene encodes a member of a family of proteins that contains a DPY30 domain. This gene locus overlaps with a closely related gene on the opposite strand. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.149A>G (p.N50S) alteration is located in exon 4 (coding exon 2) of the DYDC2 gene. This alteration results from a A to G substitution at nucleotide position 149, causing the asparagine (N) at amino acid position 50 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
