Genes affected

KCTD10 (HGNC:23236): (potassium channel tetramerization domain containing 10) The protein encoded by this gene binds proliferating cell nuclear antigen (PCNA) and may be involved in DNA synthesis and cell proliferation. In addition, the encoded protein may be a tumor suppressor. Several protein-coding and non-protein coding transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]

MYO1H (HGNC:13879): (myosin IH) Predicted to enable actin filament binding activity and microfilament motor activity. Predicted to be involved in actin filament organization and vesicle transport along actin filament. Predicted to be part of myosin complex. Predicted to be active in several cellular components, including actin cytoskeleton; microvillus; and vesicle. [provided by Alliance of Genome Resources, Apr 2022]

MYO1H Gene-Disease associations (from GenCC):

• congenital central hypoventilation syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• central hypoventilation syndrome, congenital, 2, and autonomic dysfunction

  Inheritance: AR Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
