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]

MAMLD1 Gene-Disease associations (from GenCC):

• hypospadias 2, X-linked

  Inheritance: XL Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics, G2P

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-150469967-G-T is Pathogenic according to our data. Variant chrX-150469967-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 431447.Status of the report is criteria_provided_single_submitter, 1 stars.
