Genes affected
MYADML2 (HGNC:34548): (myeloid associated differentiation marker like 2) Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
PYCR1 (HGNC:9721): (pyrroline-5-carboxylate reductase 1) This gene encodes an enzyme that catalyzes the NAD(P)H-dependent conversion of pyrroline-5-carboxylate to proline. This enzyme may also play a physiologic role in the generation of NADP(+) in some cell types. The protein forms a homopolymer and localizes to the mitochondrion. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.686G>A (p.R229Q) alteration is located in exon 3 (coding exon 1) of the MYADML2 gene. This alteration results from a G to A substitution at nucleotide position 686, causing the arginine (R) at amino acid position 229 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
