Genes affected
MAMLD1 (HGNC:2568): (mastermind like domain containing 1) This gene encodes a mastermind-like domain containing protein. This protein may function as a transcriptional co-activator. Mutations in this gene are the cause of X-linked hypospadias type 2. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2022The c.57G>A (p.M19I) alteration is located in exon 1 (coding exon 1) of the MAMLD1 gene. This alteration results from a G to A substitution at nucleotide position 57, causing the methionine (M) at amino acid position 19 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
