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 GeneticsMar 20, 2023The c.406A>T (p.M136L) alteration is located in exon 3 (coding exon 3) of the MAMLD1 gene. This alteration results from a A to T substitution at nucleotide position 406, causing the methionine (M) at amino acid position 136 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
