Genes affected

MYADML2 (HGNC:34548): (myeloid associated differentiation marker like 2) Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

MYADML2 links:

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]

Ambry Genetics

Nov 07, 2022

The c.910G>A (p.V304M) 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 910, causing the valine (V) at amino acid position 304 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
